Nanomaterials energize fuel cells

NanoDynamics in Buffalo, N.Y., is developing fuel cells that employ nanotechnology to help supply power for longer times at less weight and size than batteries or conventional fuel cells. One 50-watt solid oxide fuel-cell prototype, roughly the size of a loaf of bread, is composed of roughly 20 percent nanomaterials and can generate some 3,000 watt-hours of electricity from just 5 pounds of propane. A conventional solid oxide fuel cell given that little propane would generate only one-half to one-third as many watt-hours. more @
