      A fuel cell converts hydrogen, H2, and oxygen, O2, into water with release of electric current (electrons).
      Hydrogen hits an anode where it breaks into H atoms and free electrons. The electrons travel through a circuit and Protons (hydrogen without its electron) move to a cathode where they react with oxgen to make water and heat. The current produced can drive a car. Decent description is on wikipedia
      Hope this helps
