Adding a chemical found in antifreeze to fuel cells could provide a longer-lasting alternative to batteries in portable electronics.
Now researchers at Arizona State University in Tempe have developed a technique that could help make better fuel cells for laptops, military-grade communication devices, and, potentially, cell phones. In research presented yesterday at the American Chemical Society meeting in San Francisco, Dominic Gervasio, associate professor in the Center for Applied Nanobioscience at Arizona State, and his team showed that by adding a chemical found in antifreeze to sodium borohydride--a liquid used to store hydrogen, the molecule that powers fuel cells--they can make a longer-lasting fuel cell. The resulting fuel could power a laptop twice as long as any battery on the market, while allowing room temperature operation, unlike many other fuel cells.
