摘要:

质子交换膜燃料电池作为车载新型动力源具有广阔的应用前景而备受关注。流场板是燃料电池的核心部件之一,起分配反应气体、移除水分与杂质和传导电子等作用。目前对质子交换膜燃料电池流场方面的研究,大多针对常规流道进行了尺寸和流场布置方式的优化,部分研究在流道内部添加不同形式的堵块以增强气体传质,或将多孔介质材料应用于流场板,或设计新型的三维网格流场结构,通过此类方式来优化燃料电池的水热管理,强化传质效果以提高燃料电池的性能。本文中对这些研究进行归纳总结,并得出若干结论。

Abstract:

As a new on?board power source, proton exchange membrane fuel cell (PEMFC) has come under the spotlight due to its wide application prospect. Flow field plate is one of the core components of PEMFC, which plays the role of distributing reaction gas, removing moisture and impurities and conducting electrons. At present, most of the research on the flow field of PEMFC has focused on the optimizations of the size of routine flow channel and the layout of flow field, while some studies add different forms of blocks in the flow channel to enhance gas mass transfer, or apply porous materials to flow field plate, or design a new 3D mesh flow field structure to optimize the thermal management of water in fuel cell and intensify the effects of mass transfer for enhancing the performance of PEMFC. These researches are summarized with a few conclusions drawn in this paper.

Key words: PEM fuel cells, flow field optimization, mass transfer enhancement
