摘      要：Proton exchange membrane fuel cells(PEMFCs) are considered a promising power source for electric vehicles and stationary residential applications. However, current PEMFCs have several problems that require solutions, including high cost, insufficient power density, and limited performance durability. A kinetically sluggish oxygen reduction reaction(ORR) is primarily responsible for these issues. The development of advanced Pt-based catalysts is crucial for solving these problems if the large-scale application of PEMFCs is to be realized. In this review, we summarize the recent progress in the development of Pt M alloy(M = Fe, Co, Ni, etc.) catalysts with an emphasis on ordered Pt M intermetallic catalysts, which exhibit significantly enhanced activity and stability. In addition to exploring the intrinsic catalytic performance in traditional aqueous electrolytes via engineering nanostructures, morphologies, and crystallinity of Pt M particles, we highlight recent efforts to study catalysts under real fuel cell environments by the membrane electrode assembly(MEA).
