摘　　要：Increasing concerns with non-renewable energy sources drive research and development of sustainable energy technology. Fuel cells have become a central part in solving challenges associated with energy conversion. This review summarizes recent development of catalysts used for fuel cells over the past 15 years. It is focused on polymer electrolyte membrane fuel cells as an environmentally benign and feasible energy source. Graphene is used as a promising support material for Pt catalysts. It ensures high catalyst loading, good electro- catalysis and stability. Attention has been drawn to structural sensitivity of the catalysts, as well as polymetallic and nanos- tructured catalysts in order to improve the oxygen reduction reaction. Characterization methods including electrochemical, microscopic and spectroscopic techniques are summarized with an overview of the latest technological advances in the field. Future perspective is given in a form of Pt-free catalysts, such as microbial fuel cells for long-term development.可再生能源的开发利用是能源发展的方向.燃料电池在寻求用于替代不可再生能源的新技术过程中,日益得到关注.本文综述了近年来燃料电池催化剂的研究进展,重点介绍了石墨烯铂催化剂.石墨烯是一种有潜力的铂催化剂载体,可以提高铂催化剂的性能,使其具有更高的催化剂负载量、良好的电催化性能和稳定性.并展望了非铂催化剂,如微生物燃料电池的发展方向.
