质子交换膜燃料电池改性铂基催化剂研究进展

摘要

质子交换膜燃料电池(PEMFC)由于其工作效率高、启动速度快、环境友好等优点而倍受青睐。所用催化剂中的核心组分(金属铂)的成本和催化性能是制约其实现商业化的关键因素之一。目前有关改性铂基催化剂应用于质子膜燃料电池的研究工作主要集中在2个方面：一是通过改性催化剂的结构降低铂用柎；二是改性载体材料制备活性组分高度分散的高性能催化剂。综述柚近年来质子膜交换燃料电池改性铂基催化剂的研究进展，并对PEMFC催化剂的发展做柚展望。%The proton exchange membrane fuel cell (PEMFC) is acclaimed with the advantages of high working efficiency, starting quickly and environmental friendliness. The cost and catalytic efficiency of platinum-based catalysts, as a core component of PEMFC, are always one of the key factors limiting its large-scale commercial application. The research progress of PEMFC in recent year on modified platinum- based catalysts and the use of more superior support material, for these are two effective approaches to improve catalytic efficiency and reduce the amount of platinum used, were reviewed. The development of new catalysts for PEMFC is also prospected.
