Fuel Cell Power
So just how much power can fuel cells generate? It depends on the type of fuel cell you use, as some of the bigger (and less expensive) types of fuel cells can be stacked together to power a house. But if we assume that we’re using the Polymer Exchange Membrane Fuel Cell, which is the type of fuel cell with the most potential for the mass market, then a single fuel cell will produce 0.7 volts per reaction, at anywhere from 60%-80% efficiency. Keep in mind that hundreds of reactions go on in a fuel cell every second. The average gasoline based car runs on 20% efficiency, so this is a huge step in saving energy by itself. Factoring in cell stacking, where you can literally combine any number of fuel cells together, and you have a highly efficient energy power system that scales to any size you need. Fuel cells must be one of the most useful things ever created by man kind!
