The development of hydrogen fuel cells for vehicles, the ultimate green dream in transportation energy, is another step closer. Researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory and Argonne National Laboratory have identified a new variation of a familiar platinum-nickel alloy that is far and away the most active oxygen-reducing catalyst ever reported.
