In a fuel cell vehicle, gaseous hydrogen is pumped into the tank of a car, similar to gasoline. The hydrogen is then fed to the fuel cell “stack” – the heart of the fuel cell vehicle – where it is electrochemically converted into electricity with no combustion and zero emissions, other than water vapour. The electricity then drives an electric motor that powers the wheels. As long as you provide hydrogen, the fuel cell will continue to produce electricity. A fuel cell vehicle is highly efficient (between two and three times more efficient than today’s internal combustion engines) and operates with very little energy loss which creates excellent fuel economy.
