What is "fuel cell"?

A fuel cell is a device that creates electricity through a reaction powered by two or more chemical agents combining. Unlike a regular battery, which merely stores energy, a fuel cell actually consumes its fuel to create its power, and thus needs to be refilled periodically. Common fuel cell development for mobile devices uses methanol alcohol as the fuel agent.
