A floating, layered instrument panel for an advanced feel
Forepart pillars bear been drawn-out forrader, piece maintaining generous clearance proportions, to make a smell of place. The board is spark as a merged batch scattered to the threshold demarcation, qualification it seem to hover. Vivid colour in the cushioning accentuates the aery, broad smell.
An advanced cockpit for a futuristic experience
Course, because it’s a Honda, the FCX Lucidness is fun and sluttish to effort. The new fire cubicle multi-functional exhibit in the cockpit, e.g., features third-dimensional displays of h intake, shelling levels, drive yield and over-the-counter key entropy. The speedometer is positioned now supra the exhibit to minimize eye campaign. A concordat electronic sceneshifter that leverages the up-to-the-minute in drive-by-wire engineering has been moulded into the dial visors. Otc conception touches heighten the futurist smell, same the jump alternate beside the essence solace that activates the fire cadre lot.
Fuel cell performance meters
The luminescent cubic meters sunken into the board expose all key drive entropy. A centrally set spheric H2 time keeps raceway of h uptake. The fomite’s dials study unitedly to allow an efficacious port, providing the information production the driver inevitably.
The H2 orbicular h uptake approximate changes colouration and sizing to meditate h expenditure as impulsive weather modification. During gamy phthisis, the testicle becomes great and amber-coloured. As usance decreases, it shrinks and turns lily-livered, so dark. The h fire and barrage gauges are to the veracious of the H2 orbicular m. The fire cadre smokestack outturn approximate and bombardment turnout/mission expose are on the outer border.
Luxury from the future
Flatware accents and disconsolate acrylic in the inside threshold deal and sound empanel convey a futurist expression. High-quality materials wish wood-grain appearing paneling in the doors and lucent lightlessness lacquer headrests combining with tender colors for a voluptuous, space-age smell.
Honda Bio-Fabric, a new interior fabric made from plant material
To assistant motility outside from petroleum-based resins and early semisynthetic fibres toward plant-based fabrics, Honda created a new bounty biofabric for fomite interiors. Honda Bio-Fabric is a polyester real called poly (trimethylene terephthalate) (PTT), made by ferment clavus. Its grain and lastingness pass perfective for use in ass coverings, threshold linings, solace trays and arm rests-any portion of the fomite where the occupants bequeath apprize its bounty smell. Poly(lactic dose) (PLA) fibres made from clavus and former set biomass are victimized in cap linings, level rug and bang linings. In fact, all inner framework coverings in the Honda FCX Lucidness are made of rude, plant-based materials.
Honda Bio-Fabric: outstanding elasticity and feel
The molecular construction of PTT fiber is fine kinked in an accordion-like construction, allowing it to stretchiness more pronto than early fibres and comeback well to its archetype configuration, avoiding droopy. It too has a alone, silken spirit not base in former coverings. That is why Honda Bio-Fabric is exploited on all surfaces that occur into calculate striking with the occupants.
The production process
The 1,3-propanediol, which forms the staple for PTT fibres, is ordinarily produced by chemosynthesis. In line, Honda Bio-Fabric is made from clavus, victimisation a bio-tech agitation method. It is combined with terephthalic dose, a crude selection, to make PTT rosin, which successively is spun, made into fibres, bleached and off into Honda Bio-Fabric.
Reducing CO2 emissions
Based on the ware life-cycle from procurance of raw materials to product, Honda Bio-Fabric provides a CO2 diminution of 30% per Honda FCX Pellucidity auto, compared to ceremonious polyester made from crude products.
Plant-based resins are c indifferent eve when incinerated-the CO2 released during administration is balanced by the CO2 intent during ontogeny.
Front-row independent temperature controls
To satisfy the expectations of agiotage auto customers, the Honda FCX Pellucidity is furnished with twofold zona mood command to control optimum resident quilt and more effective use of zip.
Temperature ascendance devices reinforced rightfulness into the arse cushions and seatbacks use fans to draw air, which a thermo-electric twist so cools (by gripping heating) or warms. The air is so pursy done the seating to assert the coveted temperature patch maintaining the breathability of the urethane, permeable fizz and upholstery layers. Since this summons provides heat and chilling in engineer link with the occupants, it is quicker and more effective than air conditioning lone. Soul controls are handily set on either slope of the gist gore, providing an forward-looking feeling of comforter for the luxuriousness client.

A charge infinite, branch under-boot store comfortably and over-the-counter innovations tot to depot intensity corresponding to otc mid-size sedans.
Smaller. Higher output. The fuel cell electric vehicle has evolved
Honda fire cellphone galvanizing vehicles retain to trail the manufacture. Recognising that the fire cubicle batch is the key to the fire cellphone electrical fomite’s development, Honda has continued to meliorate execution and promotion. In 2003 Honda unveiled the Honda FC Deal, subject of sub-zero start-up and self-praise great yield feasibleness. Its figure, featuring stamped metallic separators and an redolent electrolytic membrane, revolutionised the fire cubicle. Following, Honda took up the gainsay of morphologic innovation-creating the V Catamenia FC Hatful with an archetype cadre construction that delivers reduced burthen, improved operation and eventide more contract pattern. The V Catamenia FC program is the following genesis in software excogitation. It makes compelling styling and publicity workable in a fire cellphone galvanic fomite first. It is the find in heap engineering that gives the Honda FCX Pellucidity its graceful figure.
The new V Flow FC Stack: high output in a lightweight, compact design
The V Flowing FC Heap features an all new cellphone construction that achieves a higher outturn of 100 kW, littler sizing and depress weighting, with a 50% betterment in production compactness by mass, and a 67% step-up in outturn tightness by volume, compared to the 2006 Honda FCX Concept.
Layers of cells producing lots of energy
The Honda V Flow FC Stack uses a proton exchange membrane fuel cell (PEMFC) electrical generation system that directly converts chemical energy produced in hydrogen-oxygen reactions into electrical energy.
The extremely thin proton exchange membrane (electrolytic membrane) is sandwiched between pairs of electrode layers and diffusion layers (the hydrogen and oxygen electrodes) to form a membrane electrode assembly (MEA). The MEA is enclosed between two separators to form a cell-a single electrical generation unit. Several hundred cells are stacked together to form a fuel cell stack. As with batteries, these individual cells are connected in a series to produce a high voltage.
How electricity is generated
Electrical power on demand
The main components of the fuel cell electric vehicle’s powerplant are the fuel cell stack, which generates electricity from hydrogen, the hydrogen tank, the lithium ion battery, the electric drive motor and the Power Drive Unit (PDU), which governs the flow of electricity. Because the vehicle is propelled by an electric motor, it delivers smooth, powerful acceleration and quiet operation, without the noise and vibration associated with an internal combustion engine. During start-up and acceleration-when a large amount of power is required-the electricity from the fuel cell stack to the drive motor is supplemented with electricity from the lithium ion battery to provide powerful performance. During deceleration, the drive motor works as a generator, converting kinetic energy into electricity, which is stored in the lithium ion battery along with any excess electricity produced by the fuel cells. When the vehicle is stationary, an idle stop system shuts down electrical generation in the fuel cell stack. Electricity from the lithium ion battery ensures continued operation of the air conditioner and other devices. The system optimally controls electrical power, resulting in highly efficient operation.
Another key advance: a vertical gas flow cell structure is combined with wave flow-channel separators for an even more compact, lightweight design
Until now, hydrogen and air flowed horizontally through the cells of Honda fuel cell stacks. The new V Flow FC Stack introduces a cell structure in which hydrogen and air flow vertically, and gravity is used to facilitate more efficient drainage of the water by-product from the electricity generating layer. The result is greater stability in power generation. The new structure also allows for a thinner flow channel and reduction in the stack’s size and weight. And Honda’s innovative and original wave flow-channel separators provide a more even and efficient supply of hydrogen, air and coolant to the electricity generating layer. The results are higher generating performance, optimal cooling characteristics and major reductions in size and weight. More compact, the new stack has far fewer parts and can fit into a single box. It is also much easier to manufacture.
V Flow cell structure for greater stability in electrical generation and a thinner design
In addition to allowing hydrogen and air to flow vertically, the V Flow design also means that water drainage is assisted by gravity. Water does not collect on the electrical generation layer, ensuring constant power generation. This also allows flow channel depth to be reduced by 17%-a major contributing factor in creating thinner cells and a more compact stack.
Wave flow-channel separators enable a smaller stack design
The fuel cell consists of a membrane electrode assembly (MEA)-an electrolytic membrane sandwiched between the pairs of electrode layers and diffusion layers forming the hydrogen and oxygen electrodes-which are in turn enclosed between separators containing flow channels for hydrogen, air and coolant. The V Flow FC Stack incorporates wave-shaped vertical flow channels for the hydrogen and air, with horizontal coolant flow channels weaving between them. The wave flow channels provide greater flow length per channel than straight channels, while the resulting turbulent flow within the channel promotes improved hydrogen and air distribution. As a result, the hydrogen and air are spread over the entire electrode layer, making more efficient use of the compact electricity generation layer and achieving approximately 10% higher generating performance than with straight flow channels. The horizontal coolant flow also ensures more even cooling over the entire electricity generation layer, allowing for a reduction in the number of cooling layers to half that of previous stacks. The previous stack had one cooling layer for each cell. The new stack needs only one cooling layer per two cells. This results in a 20% reduction in stack length and a 30% weight reduction-a major breakthrough in compact, lightweight stack design.
Improved heat mass allows start-up at -30˚C
Improved water drainage due to the V Flow cell structure facilitates better output immediately after start-up. The reduced coolant volume and single-box design made possible by the wave flow-channel separators results in heat mass 40% lower than previous stacks. As a result, the amount of time required to achieve 50% output after start-up at -20˚C is only one-quarter that of the previous stack. Start-up is now possible at temperatures as low as -30˚C.
Distributing the powerplant redefines the basic configuration of the automobile
The most distinctive feature of the fuel cell electric vehicle-other than the fuel cell itself-is the layout flexibility made possible by the fact that the powerplant and drive train can be distributed throughout the vehicle. In order to take full advantage of this feature, each component in the powerplant must be made extremely compact. To this end, each part of the fuel cell stack-the drive motor and gearbox, the power drive unit, the lithium ion battery and even the hydrogen tank and radiators-have been made as compact and as efficient as possible. This creates maximum freedom to optimise the position of each part to achieve the spacious, full-cabin design unique to this new fuel cell electric vehicle. The end product is the embodiment of Honda’s man maximum, machine minimum design philosophy-and the next generation in human-friendly automobiles.
The V Flow FC Stack is located inside the centre tunnel, and the lithium ion battery is placed under the rear seat. The result is a free-flowing, full-cabin design with a long wheelbase that provides the spacious and comfortable seating that customers expect in a luxury car.

Volume-efficient package and low-floor platform
The technology – a powerplant that is sure to spark a revolution in design, packaging and performance
In addition to making the fuel cell stack, drive motor and other individual components more compact, parts have been consolidated into modular units. The result is an amazingly compact and lightweight design-180 kg lighter and 45% smaller than the previous powerplant.
A significantly more compact, unified fuel cell system
The fuel cell stack is now contained in one box instead of two. This reduces the number of parts required to connect the stacks together and allows the hydrogen supply system, humidifier system and contactors to be combined into a single unit that is 65% smaller than the previous system. This makes it possible to locate the stack in the vehicle’s centre tunnel rather than under the floor, achieving a low-floor, low-height body design.
Compact, high-efficiency lithium ion battery requires less space
The vehicle’s auxiliary power source, the new lithium ion battery, delivers improved performance and energy recovery in a more lightweight, compact package. The new battery is 40% lighter and 50% smaller than the ultra-capacitor of the 2005 FCX, allowing it to be stowed under the rear seat. This gives the car more passenger space and a bigger trunk.
Three radiators integrated into one
Increased powerplant efficiency, vehicle weight reduction and improved aerodynamics have resulted in a major reduction in heat generation. The cooling air vent for the motor bay has been reconfigured and the cooling capacity of the radiators increased. These improvements made it possible to integrate the fuel cell radiator, the drive train radiator and the air conditioning condenser into a single three-layer unit. The new radiator unit requires 40% less space, contributing to the stylish short-nose design.
Unified coaxial drive motor/gearbox and PDU
An innovative configuration, with drive motor and gearbox oriented coaxially, achieves a 162 mm reduction in length as measured along the drive axis.
This coaxial motor/gearbox is further combined with the Power Drive Unit (PDU) in a unified configuration that saves another 240 mm in height. These innovations make possible the Honda FCX Clarity’s stylish, short-nose design.
Integration of functions in hydrogen tank
This creates more space for the rear seats and boot. The shut-off valve, regulator, pressure sensor and other components in the refuelling and supply system were integrated into a single in-tank module, reducing the number of parts by 74%. Tank capacity is greater, installation space efficiency is 24% better, and vehicle range is increased.
A distinctive driving experience created by the high-output electric motor
Along with uncompromising performance, the electric motor- driven Honda FCX Clarity delivers a completely different driving sensation from a conventional vehicle powered by an internal combustion engine. There are no gear changes to interrupt power delivery and the torque characteristics are smooth, making acceleration seamless and robust. This is a key part of its distinctive, premium driving feel. There is none of the vibration that comes from reciprocating pistons. There is no combustion noise-just quiet, clean, vibration free performance.
Start-up and acceleration times are comparable to that of a 2.4-litre internal combustion engine vehicle of similar size.
The Honda FCX Clarity’s high-efficiency powerplant and outstanding energy management result in an exceedingly high operating energy efficiency. Furthermore, vehicle weight reduction and superb aerodynamics contribute to an approximate 20% improvement in fuel economy. Hydrogen tank capacity has also been increased, extending vehicle range by 40%.
Higher output, high torque, higher rpms. Quieter operation in a more compact design
The new drive motor configuration was developed to deliver more powerful acceleration and a higher top speed, along with a quieter, more luxurious ride. The new rotor and stator feature a combined reluctance torque, low-loss magnetic circuit and full-range, full-digital vector control to achieve high efficiency and high output over a wide speed range.
The innovative shape and layout of the magnets in the rotor result in high-output, high-torque, high-rpm performance. These innovations deliver a maximum output of 100 kW along with impressive torque and power output density. At the same time, resonance points in the high-frequency range have been eliminated for quieter operation.
New rotor delivers high-output, high-torque, high-rpm performance
A newly designed rotor features an Interior Permanent Magnet (IPM) to lower inductance, improving reluctance torque for high-torque performance. The magnet’s high-energy characteristics also contribute to high torque and a more compact design. These innovations result in 50% higher output density and 20% higher torque density. The number of poles has also been reduced and the magnet widened to better withstand stress, allowing the yoke to wrap around the outside of the IPM. A centre rib has been installed for greater rigidity. This more robust construction allows for operation at higher rpm.
New stator contributes to high torque and efficiency
The stator features a low iron-loss electrical steel sheet and higher density windings that decrease resistance and contribute to high torque and higher output.
Number of poles reduced to eliminate resonance points and produce quieter operation
The number of magnetic poles in the rotor has been reduced from 12 to 8, eliminating resonance points within the operating rpm range. The result is outstanding quietness and higher output.
Coaxial gearbox conveys motor output directly for a major improvement in compact design
The motor’s rotor shaft features a hollow construction, with the driveshaft passing through its centre in a coaxial configuration. This arrangement, unique to electric vehicles, allows the motor and gearbox to be combined into a single, compact unit, while providing highly efficient transmission of the motor’s high-output, high-rpm power to the driveshaft. Innovative bearing design and fewer rotor oil seals result in lower friction for higher transmission efficiency, creating driving performance with a more direct feel.
Shift-By-Wire for simpler and easier operation
The vehicle’s fixed gear ratio allows for simple operation: there’s an easy-to-use shift control for forward, reverse and park that has a light touch and a short stroke. The compact shift unit features electronic control, allowing the shift lever to be installed on the dashboard. The shifter, start switch and parking switch are all easy to operate. Other operating systems are also laid out in separate zones to improve ergonomics.
Power assist and efficient regeneration with an advanced lithium ion battery
The compact, high-output lithium ion battery assists the fuel cell in powering the vehicle. The advanced battery provides a powerful supplement to the fuel cell stack’s output, powering the motor for torquey off-the-line acceleration. In addition to increasing the total energy capacity, the battery efficiently stores energy generated by the intelligent regenerative braking system, capturing 11% more kinetic energy than the ultra-capacitor used in the 2005 FCX. Some 57% of the energy of deceleration is regenerated with the new system.
As a result of increased energy storage capacity and a broader range of regeneration control, it has been possible to implement a system that regulates acceleration and reduces the need for pedal operation in downhill driving. Assessing incline and vehicle speed, the system regulates acceleration when the driver first releases the accelerator pedal, minimising the need for frequent braking. The system simultaneously adjusts the amount of regenerative braking to help maintain constant vehicle speed after brake pedal inputs. The function is similar to engine braking in a conventionally powered vehicle, but more intelligent, smoother and easier to use.
Superior chassis dynamics for greater comfort, safety and driving pleasure
Optimal geometry front and back, including carefully calibrated toe response to the suspension stroke and camber angle, maximise tyre contact with the road during cornering for highly responsive, stable handling. Optimisation of the anti-dive angle and control of vehicle behaviour during deceleration contribute to an even, comfortable ride.
The lowered front suspension adds to the visual impact of the short-nose design. In addition to the implementation of a 5-link double-wishbone rear suspension, forged aluminium lower arms, high-capacity trailing arm bushings and reduced unsprung weight smooth out bumps in the road.
Responsive electric power steering for a 5.4m turning radius and tight cornering
Along with a newly implemented brushless motor with increased output, the front double-wishbone suspension helps facilitate tight cornering and delivers a 5.4m turning radius-a very tight turning radius given the vehicle’s long wheelbase. The low inertia of the motor and minimal friction of the suspension when turning contribute to smoother steering. And a tilt-and-telescopic steering wheel provides an optimal steering position for a wide range of drivers.
Vehicle Stability Assist (VSA) integrated with electric power steering (EPS) for enhanced handling
The Honda FCX Clarity features an integrated braking, traction control and electric-controlled steering system that works in concert to help the driver maintain control of the vehicle in emergency manoeuvres and in varying road conditions. Working in conjunction with the vehicle’s anti-lock brakes, Traction Control System (TCS) with slideslip control and Vehicle Stability Assist (VSA), the Electric Power Steering (EPS) enhances steering force for even better handling.
Complementing the linear torque control of the drive motor, TCS provides enhanced grip and control in acceleration
Increased motor torque responsiveness during TCS operation has made a major contribution to suppressing excessive tyre slip. Improvements to the total system deliver even more precise torque transmission and improved grip for confident acceleration even on slippery surfaces, and improved control in acceleration.
Striving to protect vehicle occupants
To enhance occupant protection in a collision, Honda has implemented innovative body technology with a network of frame structures in the front of the vehicle along with additional safety precautions appropriate to a fuel cell electric vehicle. The vehicle is designed to comply with all applicable federal motor vehicle safety standards.
The fuel cell system and hydrogen tank are protected from collisions at every angle.
A body designed for the V Flow platform with the rigidity to withstand collisions from all angles
Taking full advantage of the distributed powerplant layout, we have optimised the body structure. To help protect occupants in the event of frontal collisions, the straight front-side frame, upper frame and lower structural parts are designed to disperse and absorb impact energy. Energy is dispersed through the front pillars and floor. The lower structural members are designed to help prevent misalignment with the impact-absorbing parts of the other vehicle. Along with an energy-absorbing upper frame, they efficiently disperse energy over a wider area. This design is intended to both reduce the impact forces on Honda FCX Clarity occupants as well as on the other vehicle. The enhanced rigidity of the body also increases overall vehicle refinement.
The impact-absorbing front-end design helps enhance pedestrian protection
To help protect pedestrians, we have designed the Honda FCX Clarity’s fenders, bonnet hinges, wiper pivots and other components to more efficiently absorb collision impact.
