FCEV

Also called: fuel cell electric vehicle, hydrogen fuel cell vehicle A fuel cell electric vehicle, or FCEV, uses a fuel cell to generate electricity for the electric motor that propels the vehicle. Road-going FCEVs normally store compressed hydrogen onboard and combine it with oxygen from the air in the fuel-cell system. The vehicle has an electric drivetrain, but it is refuelled with hydrogen rather than relying on plug-in charging for its main energy supply. A small battery can buffer energy and recover power through regenerative braking. FCEVs have zero tailpipe CO2 under current UK vehicle classifications. The lifecycle emissions depend on how the hydrogen is produced and supplied.
