Abstract

Fuel cells, including hydrogen–oxygen fuel cells, methanol fuel cells, formic acid fuel cells, etc., as a kind of very promising energy device, have attracted global attention due to their high energy conversion efficiency and environmentally friendly emissions. However, fuel cells are still facing the challenges of poor performance, high cost, and limited durability. Understanding the basic principles of electrocatalytic reactions provides new insights into the selection and design of fuel cell electrocatalysts with excellent performance and durability. Herein, the latest progress of Pt-based precious metal catalysts in fuel cells is focused upon, including reasonable structural design and electrochemical reaction mechanism, and the current status of efficient utilization of Pt-based catalysts with different structures is reviewed, such as nanowires, hollow structures, nanosheets, high-index nanocrystals, atomic-scale dispersion, alloy structures, and carrier effects. Finally, the personal perspectives on the future directions for efficient utilization of Pt in fuel cells are proposed.
