Researchers at Washington State University have developed a new way to make low-cost, single-atom catalysts for fuel cells – an advance that could make important clean energy technology more economically viable. Hydrogen fuel cells are critical for the clean energy economy as they are more than two times as efficient at creating electricity than polluting combustion engines. Their only waste product is water.

However, the high price of the platinum-based catalysts that are used for the chemical reaction in fuel cells significantly hinders their commercialization. Instead of the rare platinum, researchers would like to use nonprecious metals, such as iron or cobalt...
