2009 Honda FCX Clarity



From the start, Honda engineers designed this car to be tons of fun to drive. Acceleration in the FCX Clarity is smooth and powerful for a great overall driving experience.

Information gleaned from multiple generations of Honda fuel cell vehicles pays off right now. Compared to the previous model, the powertrain on this next-generation FCX Clarity:
  • Is over 397 pounds lighter
  • Has 120% better power-to-weight ratio
  • Is 20% more fuel efficient
  • Has a powertrain that is 45% more compact and 10% more energy-efficient
Free and Clear
First, the basics: a fuel cell vehicle is powered by an electric motor running on electricity generated by a hydrogen-powered fuel cell stack. The Honda E-Drive electric motor lets you drive with peace of mind knowing that you are helping to reduce the amount of CO2 being released in our atmosphere. The compact coaxial motor is quieter and works at higher rpm, for greater efficiency and speed.

Get Vertical
The Vertical Flow (V Flow) fuel cell stack is one of Honda’s greatest breakthroughs in this area. The new design is smaller, allowing for better packaging efficiency. With a smaller stack, there’s room for more people. This ingenious design allows higher cell voltage stability and reduces the amount of heat generated. Gravity also helps with drainage of the excess water.

Added Power
The compact, high-efficiency lithium-ion battery pack is used as a supplemental power source capturing lost energy during deceleration and braking. The new lithium-ion battery delivers improved performance and energy recovery in a more lightweight, compact package. The new battery is significantly lighter and 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.

 

Low Profile

Stylish? Definitely. It’s time to take another look at the FCX. This new model has a lower floor and sleeker overall design thanks to integration of the more compact stack and smaller powertrain. Thin A-pillars allow better visibility. A flat-bottom underbody reduces aerodynamic drag and increases efficiency.

Hydrogen Safety

Sensors are located throughout the vehicle to provide a warning in the unlikely event of a hydrogen leak. Should such a leak occur, the ventilation system is activated and an automatic system closes the main cut-off valves on the hydrogen tank or supply lines as necessary. The high-voltage lines are electrically isolated. Sensors provide a warning in case of grounding. In the event of a collision, high-voltage contactors shut down the source power line. Repeated flood and fire testing have confirmed a very high level of safety and reliability.

Refueling Safety
Honda has taken safety precautions with regard to refueling safety. To prevent reverse flow from the tank, the hydrogen filler inlet has an integrated check valve. The fuel intake mechanism is also designed to prevent contamination by other gases or the connection of nozzles designed for hydrogen stored at incompatible pressure levels.

The FCX Clarity is not an experiment or prototype. This is a full-featured vehicle that can be driven with both pride and confidence. Learn more about how the FCX Clarity helps keep you safe in a crash.
