Honda’s FCX Clarity FCEV is much more efficient than conventional gasoline-powered vehicles 
in converting chemical energy into power. The Honda FCX Clarity FCEV is not an experimental or prototype vehicle.
In gasoline-powered vehicles, fuel (gasoline) is used to heat and expand air, which then drives the engine’s pistons and crankshaft.
Fuel cell vehicles, on the other hand, are much more efficient, because the conversion of fuel (hydrogen) to electricity, used to power the electric drive motor, is a more direct electrochemical process. Water is a by-product.
And since the FCX Clarity FCEV has significantly fewer components in the drive system, no pistons and no camshafts, the energy loss from these systems is eliminated.
Vehicles that use hydrogen fuel cell technology instead of gasoline are about the cleanest around because they emit only water vapor into the air. They also use hydrogen from domestic energy sources, reducing our dependence on oil. And driving fuel cell vehicles significantly reduces the amount of carbon dioxide emissions, helping to slow the increase in greenhouse gases.
To develop a fuel cell vehicle worthy of the Honda name, our engineers worked tirelessly to ensure that the FCX Clarity FCEV was:
* Safe for the public
* Operable in freezing weather
* Able to drive a reasonable range before refueling
* Easy to refuel
* Sporty and fun to drive
* Spacious and comfortable
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. In the event of a collision, the system controller automatically shuts off the flow of hydrogen and electric current. 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.
