Fuel cells in graphene

Researchers at the laboratory of the U.S. Department of Energy and Princeton University have found a way to combine the graphene with indium tin oxide. Specifically, it lowers manufacturing costs and increases battery longevity. The principle is known. A fuel cell uses a chemical reaction between oxygen and hydrogen to create an electric current passing produces water and heat.

This is the reverse of electrolysis is taught in college. A good fuel is composed of a chemical catalyst, usually a metal such as platinum and a support on which the metal to optimize the reaction. Using graphene, a carbon sheet one atom thick with a honeycomb structure, it is possible to provide better support to the plate, improving performance.

The scientists now plan to test their concept outside their laboratories.
