摘　　要：相较于膜电极和双极板而言,密封材料是当前质子交换膜燃料电池研究领域被忽视被研究的对象。密封材料虽不参与电池电化学反应,但也是决定电池关键因素之一,其性能好坏直接影响电池发电效率和使用寿命。本文主要介绍了PEMFC密封材料的种类和技术指标要求,并综述了密封材料国内外研究现状。Compared with membrane electrode assembly(MEA)and biopolar plate(BP),the significance of sealing materials has been underestimated.Despite the sealing material does not directly contribute to the cells’electrochemical reactions,the performances are the crtitical factors that impact the efficiency and lifetime of the cells stack.This article describes several typical sealing materials and their current research status.
