THE FUEL CELL

In very simple terms, a fuel cell is a device that converts chemical energy from hydrogen and oxygen into electrical energy and produces an electrical current. It is similar to a battery in that it has an anode and a cathode. However, a battery is only capable of storing power, whereas the fuel cell can generate it, so long as hydrogen, the fuel, is being supplied. As such, the fuel cell system also has similarities to an internal combustion engine, except that it operates very efficiently at low temperatures and with minimal moving parts. In the process of electrochemical conversion to create electricity, the only by-products of the fuel cell are water and heat.
