A prototype fuel cell runs on a wide range of fuels without turning up the heat.
Fuel cells are the most efficient way to convert chemical energy into electricity. But most either operate at high temperatures or require very pure hydrogen fuel. Superprotonic, a startup company in Pasadena, CA, is developing a fuel cell that can handle dirty hydrogen at relatively low temperatures. It could thus use hydrogen produced from other fuels--such as natural gas or ethanol--by a simple device called a "reformer."

Smokeless stack: This prototype stack of solid-acid fuel cells made by Superprotonic puts out 50 watts of power--enough to recharge a battery or power small electronic devices. The cells can run on a range of fuels, including natural gas and biofuels. Credit: Superprotonic
