摘　　要：流场板是PEM燃料电池重要元件之一 ,它能够均匀分配电池放电所需的燃料与氧化剂 ,保证电流密度分布均匀 ;能使电池生成水在反应尾气吹扫和夹带下顺利排出。本文对流场板的各种结构与性能做一综述 ,主要涉及了多孔材料流场板、点状流场板、网状流场板及蛇型流场板等 ,其中对蛇型流场板做了较详细的介绍。Flow field plate is one of the important parts in proton exchange membrane fuel cell(PEMFC),by means of which, we can distribute oxidant and fuel stream in both of cathode and anode sides separately so as to achieve equal current density and remove liquid water accumulated at cathode. Various kinds of flow field plates in PEMFC, such as porous material plate, pin type, mesh type and serpentine type were reviewed. Among them, serpentine type flow field plates are mentioned in detail. This paper is referable for research and design of PEMFC.
