Changing fuel cell catalyst shape would dramatically increase efficiency, lower cost

November 17, 2016
Jagged platinum nanowires are made by removing nickel from a platinum-nickel alloy.

UCLA professors Xiangfeng Duan, Yu Huang, and William Goddard have engineered more efficient platinum-reliant fuel cells, resulting in increased reaction efficiency and power generation rate. Because the only byproduct of platinum-powered fuel cells is water vapor, they present an appealing renewable technology for vehicles. Duan, Huang, and Goddard’s research will help to make this technology more cost-efficient, rendering its implementation more viable on a practical scale.
