Abstract
Johnson Matthey, Orchard Road, Royston, Hertfordshire SG8 5HE, UK Email: *oliver.holton@matthey.com; **joe.stevenson@matthey.com Proton exchange membrane fuel cells (PEMFCs) dominate the transportation fuel cell market and platinum (Pt) is the catalyst material used for both anode and cathode. This review sets out the fundamentals of activity, selectivity, stability and poisoning resistance which make Pt or its alloys the best available materials to use in this application. It is clear that Pt is the only element which can meet the requirements for performance while avoiding slow reaction kinetics, proton exchange membrane (PEM) system degradation due to hydrogen peroxide (H2O2) formation and catalyst degradation due to metal leaching. Some of the means by which the performance of Pt can be enhanced are also discussed.
英国赫特福德郡罗伊斯顿乌节路SG8 5HE Johnson Matthey邮箱:*oliver.holton@matthey.com;**joe.stevenson@matthey.com质子交换膜燃料电池(pemfc)主导着运输燃料电池市场，铂(Pt)是用于阳极和阴极的催化剂材料。本文综述了Pt或其合金在活性、选择性、稳定性和耐毒害性方面的基本原理，这些基本原理使Pt或其合金成为这方面应用的最佳材料。显然，Pt是唯一能够满足性能要求的元素，同时避免反应动力学缓慢，避免过氧化氢(H2O2)形成导致质子交换膜(PEM)系统降解和金属浸出导致催化剂降解。本文还讨论了提高Pt性能的一些方法。
