Platinum-alloy Materials for highly efficient oxygen reduction reaction in fuel cell

Abstract

 Global climate change and the overuse of fossil fuels have become the most serious challenges of the day. As a result, the search for cleaner and more efficient energy conversion technologies has become more imminent. The advantages of f proton exchange membrane fuel cells, such as zero emission, simple structure and low cost, have attracted the attention of a wide range of scholars. However, the selection of ORR catalysts in fuel cells is the key to its development. Therefore, this paper presents a review of platinum alloy materials for efficient oxygen reduction reaction in proton exchange membrane fuel cells. The advantages and disadvantages of different materials are explored, analyzed and discussed.
