A fuel cell combines hydrogen with oxygen (from air) in a chemical reaction. Unlike technologies which "burn" fuel, with fuel cells the conversion takes place electrochemically without combustion. Fuel cells target a range of sizes from about ½ kW upwards, and are expected to have applications for distributed power generators by the early part of the 2010s. You can see Fuel cell powered buses in London and other towns already.
Fuel cells can be run on a wide variety of fuels, and importantly, fuel cells make fuels last longer. When run on pure hydrogen fuel generated by renewable energy sources fuel cells produce no carbon or other toxic emissions at all, and can therefore help tackle environmental and energy security challenges.

Fuel cells for domestic use are currently under development.
