Hydrogen Fuel Cells
As a lot of the alternative energy sources, Hydrogen Fuel Cells are a relatively new technology that was originally developed for the space program.
In fact they are similar to batteries in that they produce electricity by a chemical reaction combined with an electrical charge. The difference with batteries is that power is only produced while the fuel cell is being fed with hydrogen. You can find more in depth information about their workings on our site.
The amount of electricity the fuel cell produces depends on the size of the cell as well as the rate of flow of the hydrogen. The chemical reaction between hydrogen and the air produces electricity, water and heat.
The heat output from a fuel cell, however, is quite low when compared with othe...
