What Is A Fuel Cell?

The easiest way to understand fuel cells is to think of them as a cousin to the ordinary battery. Both produce electricity through electrochemical reactions. The difference lies in a fuel cell's ability to constantly produce electricity as long as it has a source of fuel where a battery needs to be recharged. Consequently, since a fuel cell does not store energy internally, a fuel cell will not "run down" like a battery. Fuel cells directly convert the fuel into electricity where a battery has to replenish its electricity from an external source.
