Big step for next-generation fuel cells and electrolyzers

A big step in the development of next-generation fuel cells and water-alkali electrolyzers has been achieved with the discovery of a new class of bimetallic nanocatalysts that are an order of magnitude higher in activity than the target set by the U.S. Department of Energy (DOE) for 2017. The new catalysts, hollow polyhedral nanoframes of platinum and nickel, feature a three-dimensional catalytic surface activity that makes them significantly more efficient and far less expensive than the best platinum catalysts used in today's fuel cells and alkaline electrolyzers. This research was a collaborative effort between DOE's Lawrence Berkeley National Laboratory (Berkeley Lab) and Argonne National Laboratory (ANL).
