Hydrogen fuel cell has the advantages of high efficiency, high energy density, and zero emissions, and is a key frontier technology for a sustainable future. However, the large-scale commercial application of fuel cells is still facing bottlenecks such as high cost, which is mainly due to the use of expensive Pt- d catalysts. In this talk, the development of i) low-Pt catalysts (e.g., nanowires, nanotubes, alloys and single atoms) and ii) non-Pt catalysts (e.g., Fe/N/C) catalysts to significantly lower the cost and increase the performance of the catalysts in fuel cells will be presented. Our recent work on green hydrogen production, including Pt single atom and non-precious  l catalysts for freshwater/seawater splitting will be introduced as well.
