2. FUEL CELLS
 Electrochemical device
 Converts chemical energy into low voltage DC electrical energy
 Also described as a primary battery

4. HYDROGEN OXYGEN FUEL CELL
 Hydrogen is the fuel and oxygen is the oxidiser.
 3 chambers separated by two porous electrodes, anode and cathode.
 Middle chamber is filled with electrolyte.
 At high temperatures, electrolyte act as filter
 By product is water.

6. ADVANTAGES
