摘　　要：质子交换膜燃料电池作为清洁、环境友好型的新能源被认为很有应用前途。燃气中CO(约1%)的存在会导致燃料电池铂电极中毒,CO选择性催化氧化是被认为将CO脱除最重要的方法之一。Cu-Ce作为非贵金属催化剂,在富氢气中去除CO的应用中具备极高的潜力。本文综述了Cu-Ce催化剂的研究进展,介绍了影响催化剂性能的几种因素,梳理了制备方法、铜含量、载体形状等对催化剂活性的影响效果及其原因,概述了近几年比较典型Cu-Ce催化剂的稳定活性实验研究结果。最后指出未来研究的关注点。Proton exchange membrane fuel cell is considered as a clean and environmentally friendly new energy source which may be widely used in the near future.The presence of CO(about 1%)in the gas can cause poisoning of the platinum anode.CO preferential oxidation is considered as one of the most effective method for removing CO from H2-rich streams.As a non-noble metal catalyst,Cu-Ce has a high application potential for CO removal in hydrogen-rich.In this paper,the research progress of Cu-Ce catalysts is reviewed.Several factors affecting the performance of the catalyst are introduced.The effect of preparation methods,copper content and carrier shape on the activity of the catalyst and their reasons were reviewed.The experimental results of stability of typical Cu-Ce catalysts in recent years were reviewed.
