FUEL CELL CARS Fuel Cell cars are a major part of the fleet of Zero-Emission Vehicles. The fuel cells are fueled with pure hydrogen and hence they are considered to be zero emission vehicles. Fuel cells have been used on spacecraft for many years to power electric equipment. These are fueled with liquid hydrogen from the spacecraft ’s rocket fuel tanks. Basic Mechanics Fuel cell vehicles turn hydrogen fuel and oxygen into electricity. The electricity then powers an electric motor‚ just like
