Not being precious about fuel cells

Avoiding the use of costly and rate platinum as the basic ingredient of fuel cells catalysts might be possible thanks to the development of an alternative based on cobalt and graphene developed by researchers at Brown University. Shouheng Sun and his colleagues have coated a graphene sheet with cobalt and cobalt-oxide nanoparticles, which they say can catalyze oxygen reduction almost as well as platinum but have the distinct advantage of being far more durable. The optimization of this new catalyst might displace platinum and lead to the more widespread adoption of this essentially nineteenth century technology by using 21st century materials.
