A fuel cell is a way to convert a fuel such as hydrogen or methane directly into electricity through a chemical reaction called electrolysis.<ref name="rf1">http://sci-toys.com/scitoys/scitoys/echem/fuel_cell/fuel_cell.html</ref> Each fuel cell contains two electrodes, one positively charged (the anode) and one negatively charged (the cathode), and an electrolyte that carries charged particles from one electrode to the other.<ref name="rf2">http://americanhistory.si.edu/fuelcells/basics.htm</ref> There is also a catalyst that increases the rate of the reaction at the electrodes. Fuel cells that use hydrogen react with oxygen to form the byproduct of water, making them useful for high tech applications where clean power is needed. To understand how a fuel cell works, you can build a simple electrolytic cell with mostly common household materials. | A fuel cell is a way to convert a fuel such as hydrogen or methane directly into electricity through a chemical reaction called electrolysis.<ref name="rf1">http://sci-toys.com/scitoys/scitoys/echem/fuel_cell/fuel_cell.html</ref> Each fuel cell contains two electrodes, one positively charged (the anode) and one negatively charged (the cathode), and an electrolyte that carries charged particles from one electrode to the other.<ref name="rf2">http://americanhistory.si.edu/fuelcells/basics.htm</ref> There is also a catalyst that increases the rate of the reaction at the electrodes.
