Definition of FUEL CELL. : a device that continuously changes the chemical energy of a fuel (as hydrogen) and an oxidant directly into electrical energy.
A fuel cell vehicle (FCV) or fuel cell electric vehicle (FCEV) is a type of vehicle which uses a fuel cell to power its on-board electric motor. Fuel cells in vehicles create electricity to power an electric motor, generally using oxygen from the air and compressed hydrogen. A fuel cell vehicle that is fueled with hydrogen emits only water and heat, but no tailpipe pollutants, therefore it is considered a zero-emissions vehicle. Depending on the process, however, producing the hydrogen used in the vehicle creates pollutants.
