A Fuel Cell Electric vehicle is a hydrogen-powered vehicle that converts hydrogen into electricity. Unlike combusting fuel in an internal combustion engine (like petrol or diesel), in an FCEV hydrogen is converted to electricity through an electrochemical reaction. The electricity then powers an electric motor, which provides motive force. The only emission of an FCEV is water.
Examples: Toyota Mirai, Hyundai Nexo, Hyundai iX35 FCEV
