Hydrogen-powered cars, power stations and portable chargers all rely on fuel cells. At the heart of each fuel cell is a catalyst that speeds up the reaction between hydrogen and oxygen to produce electricity and water. These catalysts are typically made of platinum—which costs nearly as much as gold. Researchers from Southern Federal University, together with colleagues from Skoltech (part of the VEB.RF Group), the Institute of Catalysis of the Siberian Branch of the Russian Academy of Sciences, and Bauman Moscow State Technical University, have found a way to make this key component both cheaper and better. They developed a catalyst from a five-metal alloy that retains its activity even after 10,000 operating cycles.
