质子交换膜燃料电池中，空气电极上进行的氧还原反应动力学过程迟缓，是贵金属铂催化剂的主要消耗反应，但铂储量有限、成本过高、稳定性差等缺点严重制约了质子交换膜燃料电池大规模商业化应用. 开发低载量、高催化活性、高稳定铂催化剂是降低燃料电池成本的重要途径之一. 本文以作者课题组近年工作为基础，综述了铂基催化剂的稳定性研究，以及以铂合金为代表的低铂氧还原反应催化剂的最新研究进展. 文章重点讨论了催化剂的结构设计与制备，并对未来氧还原催化剂的发展提出了展望

One major challenge for a large-scale commercialization of the proton-exchange membrane fuel cells (PEMFCs) technologies that enable a shift to ‘zero-emission’ personal transportation, is the expensive and unstable Pt catalysts, which are mainly used to catalyze the sluggish kinetics of the oxygen reduction reaction (ORR) occurred on the air electrode of PEMFCs. Many research works have targets to improve the stability of Pt-based catalysts and to construct Pt/transitional metal alloys with low Pt loading amount. Herein, we provide a minireview for the Pt-based ORR catalysts based on our recent work, which covers a brief background introduction, the stability improvement of pure Pt catalysts, the construction of Pt-alloy type catalysts and a future perspective. It is believed that the alloy catalysts with a sophistical structure design at an atomic level owns a promising future prospect.
