Brookhaven lab scientists stabilize platinum electrocatalysts for use in fuel cells
Platinum is the most efficient electrocatalyst for accelerating chemical reactions in fuel cells for electric vehicles. In reactions during the stop-and-go driving of an electric car, however, the platinum dissolves, which reduces its efficiency as a catalyst. This is a major impediment for vehicle-application of fuel cells. view more (2007-01-15)
LSU professors work to improve efficiency of ethanol fuel
Lowering fuel emission levels is a topic facing constant scrutiny by the global public.
