Fuel cell vehicle characteristics
This diagram is for illustrative purposes only and may differ from the
actual vehicle.
Fuel cell vehicles efficiently use electricity, which is generated
by a chemical reaction between hydrogen and oxygen in a fuel
cell stack, and electricity charged in a traction battery to drive
the electric motor (traction motor).
The fuel is H
2 (compressed hydrogen gas), so the exhaust is
only water and water vapor. As they do not release emissions
such as CO
2 (Carbon Dioxide) and NOx (Nitrogen Oxides), fuel
cell vehicles are environm entally friendly vehicles.
