Abstract:
Fuel cells are the ideal devices to utilize hydrogen,however,the requirement of Pt hinders their development. This review focuses on the progress on the development of the platinum-free fuel cell catalysts. For proton exchange membrane fuel cells,this review mainly focuses on the cathode,due to the low Pt requirement on the anode. For hydroxide exchange membrane fuel cells,both anode and cathode require high Pt loading,thus the achievement on the both sides are reviewed. Finally,the future development of platinumfree fuel cell catalysts is prospected,aiming to provide guidance and reference for the research and long-term development.
