Researchers Found a Durable, Cheaper Alternative To Platinum For Hydrogen Fuel Cells

There’s a new contender in the race to find an inexpensive alternative to platinum catalysts for use in hydrogen fuel cells. Brown University chemist Shouheng Sun and his students have developed a new material — a graphene sheet covered by cobalt and cobalt-oxide nanoparticles — that can catalyze the oxygen reduction reaction nearly as well […]
