Fuel cells are placed into a fuel cell stack to provide the amount of energy required. Each fuel cell produces roughly 0.7 of a watt of electricity. .

             The Ballard Fuel Cell generates power much differently than the internal combustion engine and the storage battery, which are the two most common forms of power found in our society. The fuel cell has the advantages of both, without the problems of either.

             Internal combustion engines work by burning fuel to create heat, which is then converted into mechanical energy which runs the car. This conversion of energy is extremely ineffective because a large amount of heat is lost, and energy is lost because of friction. Ballard Fuel Cells, on the other hand, convert fuel directly into electricity, making them two or three times more effective than the obsolete internal combustion engine. Fuel cells use fuel tanks very similar to the ones found on internal combustion engines, and will operate continuously as long as hydrogen and pure oxygen are supplied. Unlike the internal combustion engine, however, fuel cells do not burn fuel and therefor do not produce any harmful pollutants. .

             The second most commonly used form of producer of energy is the battery. Batteries store energy, and do not create power. They consume themselves to create power, unlike the fuel cell or internal combustion engine which consume fuels to create power. Battery electrodes store the fuel producing electricity electrochemically as the battery discharges consuming its electrodes. Batteries and fuel cells are both electrochemical (combustion is not used) devices that have high efficiencies, are very quiet, and do not pollute the environment. The only problem with batteries is that they only store, and do not produce power. Batteries rely on central power plants such as Duracell or Energizer to recharge them, therefor batteries shift the pollution, efficiency and cost problems to the central power plants.
