A little gold can reduce the Pt loading in fuel cells

A challenge in the development of polymer-electrolyte membrane fuel cells is the durability and electrocatalytic activity of platinum-based electrocatalysts. The sluggishness of the oxygen reduction reaction (ORR) causes the fuel cell performance to be limited by the cathodic reaction, and…
