Tiny fuel cell might replace batteries in laptop computers, portable electronics: "The generator uses a special solution containing borohydride, an alkaline compound that has an unusually high capacity for storing hydrogen, a key element that is used by fuel cells to generate electricity. In laboratory studies, a prototype fuel cell made from this generator was used to provide sustained power to light bulbs, radios and DVD players, the researchers say.

The fuel cell system can be packaged in containers of the same size and weight as conventional batteries and is recharged by refilling a fuel cartridge, they say. Research on these battery replacement fuel cells, which they claim are safer for the environment than regular batteries, was described today at the 232nd national meeting of the American Chemical Society.
