2009 Honda FCX Clarity Preview

Hardware
The 2009 Honda FCX Clarity is powered by a fuel cell stack that uses hydrogen to produce electricity, which in turn powers an electric traction motor that drives the front wheels. A regenerative braking system, similar to the system found in hybrids and battery-electric vehicles, allows the motor to generate electricity as the car slows down. This power is stored in a battery and is used to supplement the fuel cell as needed. Because the FCX Clarity uses an electric motor to power the wheels, there is no need for a conventional transmission. Total power output is 100 kilowatts, equivalent to about 134 hp.

The FCX Clarity's styling takes advantage of the packaging possibilities of a fuel-cell vehicle. The electric traction motor is located between the front wheels, allowing a short, low hood. The “V Flow” fuel cell stack is mounted between the front seats, inside a center tunnel similar in size to that found in conventional cars. The battery is just ahead of the rear axle, while the single hydrogen tank is located between the rear wheels, providing space for a traditional trunk.
