摘要：
Currently, the carbon supported Pt and Pt alloy nanoparticles (NPs) are still the primary electrocatalysts for hydrogen fuel cells. However, the large-scale commercialization of hydrogen fuel cells is impeded due to the poor durability, high cost and low reserves of Pt. Hence, the development of low-cost, high-performance non-Pt or low-Pt electrocatalysts is a key for the commercialization of hydrogen fuel cells. With the focus on the cost, durability and poisoning of electrocatalysts, this paper reviews the latest research progress in improving the activity of anode catalysts and reducing the cost of cathode catalysts. Moreover, this paper also summarizes the influence of the composition, structure and size of nanoparticles on the activity and durability of the catalysts. Finally, we provide guidance for the development of fuel cell catalysts, that is, the application of in-situ characterization techniques to unravel the hydroxide (HOR) mechanism in alkaline medium, and the development of facile and efficient strategies to fabricate the small size and highly order intermetallic Pt alloys catalysts. © 2021, Chemical Industry Press Co., Ltd.
