摘　　要：质子交换膜燃料电池(PEMFC)能直接将化学能转换为电能, 具有能量转换效率高、环境友好、启动快等优点. 其中电催化剂是决定PEMFC性能、寿命及成本的关键材料之一. 目前所采用的Pt催化剂成本较高, 是阻碍其商业化的主要因素. 而Pt纳米线电催化剂的Pt利用率和催化剂活性高, 抗CO毒性以及耐久性好. 本文综述了Pt纳米线电催化剂的制备及其电化学催化性能的研究现状.The proton exchange membrane fuel cell（PEMFC） directly converts chemical energy into electricity with a high energy conversion rate,environmental friendliness,and the ability to start working quickly.The key material that determines the performance,lifetime,and cost of the PEMFC is the electrocatalyst,but the Pt catalyst used is very expensive,which is the major factor limiting the commercial use of the PEMFC.The Pt nanowire catalyst has demonstrated good performance in improving the utilization ratio of Pt,electrochemical activity,CO tolerance,and durability.This article reviewed the preparation and characterization of the Pt nanowire catalyst and its electrochemical activity.
