摘　　要：质子交换膜燃料电池(Proton Exchange Membrane Fuel Cell,PEMFC)是一种清洁无污染、热效率高、能量密度高的能源装置。极板组是PEMFC的核心部件,其内部流场承担着气体均匀分布、水热管理、传导电子的重要作用。由于金属泡沫流场内部是细微通孔结构,可以提高气体传输均匀性和改善水热管理等性能。本文综述了金属泡沫流场极板组的研究进展,分析探讨了金属泡沫流场的尺寸和孔隙率对气体传输、电子传输和水热管理等方面的影响,同时展望了在现有研究较为成熟的疏水涂层中加入金属颗粒、使用复合型金属泡沫流场和优化通孔结构等方式来提高电导率和排水性能,减缓腐蚀的研究方向。Proton Exchange Membrane Fuel Cell(PEMFC)is a kind of clean and pollution-free energy device with high thermal efficiency and high energy density.The plate group is the core component of PEMFC,and the internal flow field plays an important role in gas uniform distribution,hydrothermal management and electron conduction.Due to the fine pore structure inside the metal foam flow field,the uniformity of gas transmission and the hydrothermal management can be improved.This paper reviews the progress of research on metal foam flow field pole plate sets,analyzes and discusses the effects of size and porosity of metal foam flow fields on gas transport,electron transport and hydrothermal management,and also looks forward to the incorporation of metal particles in more mature coatings,the use of composite metal foam flow fields and optimization of through-hole structures to improve electrical conductivity and drainage performance and mitigate corrosion phenomena.
