Developments made in the lab of Vijay Ramani, professor and researchist at the McKelvy School of Engineering of Washington University in St. Louis, have led to the discovery of a bifunctional oxygen electrode catalyser, enabling the creation of a both fuel cell and electric battery powered device. The lab's researchers found how to balance the use of both platinum and lead to efficiently catalyse hydrogen and oxygen.
