A fuel-cell vehicle is an electric vehicle. In a battery-electric vehicle, a battery converts chemical potential energy to electricity, which drives an electric motor. In a fuel-cell vehicle, a fuel cell converts chemical potential energy into electricity, which dries an electric motor.
Curious. Doesn’t a fuel cell system have a battery, too? Make sense to use the deceleration/braking to charge the battery and the fuel cell to charge it and both to drive the car.
After all, electricity is electricity.
