Fuels for Fuel Cells

As an energy conversion device, fuel cells generate the electrical power from a wide range of chemical fuels. Among them is hydrogen the most popular fuel due to its fastest kinetics and highest conversion efficiency. In this Chapter, hydrogen generation via electrolysis, steam reforming and other processes is first introduced and hydrogen storage techniques are reviewed. Other hydrogen carrying fuels like hydrocarbon and alcohols are also addressed. The electrochemistry, catalysis, catalyst materials as well as environmental issues are discussed.
