摘　　要：气体扩散层在质子交换膜(PEM)水电解池中有着支撑膜组件、供给反应水、移除气体产物以及降低欧姆电阻的重要作用。PEM水电解池阳极区具有酸性、富氧且高电位的工作环境,对阳极区的气体扩散层具有严苛的要求。气体扩散层结构特性、导电性与耐腐蚀性是决定其电化学性能的关键。本文总结了可用于PEM电解池阳极气体扩散层的材料,简述了其结构特性对PEM电解池电化学性能的影响,分析了各种镀层材料在提高气体扩散层的导电性、耐腐蚀性以及电解池阳极氧析出反应(OER)性能方面的作用。最后,展望了气体扩散层在降低成本和提高电解池性能方面的研究趋势。In the proton exchange membrane(PEM)electrolysis cell,the gas diffusion layers play an important role in supporting the membrane components,supplying water for the reaction,removing gas bubbles from catalyst layers,and decreasing the electronic resistance.The anode at the PEM electrolysis cell works in an acidic,oxygen-rich,and high-potential environment.Therefore,a cell with excellent electrochemical performance requires a gas diffusion layer with a suitable structure and high corrosion resistance.This review categorizes the anodic titanium-based gas diffusion layers used in the PEM electrolysis cell,and briefly describes the way their structural characteristics affect the electrochemical performance of the cell.In addition,this review discusses how various coating materials improve the electrical conductivity and corrosion resistance of the gas diffusion layer and the performance of the oxygen evolution reaction in the cell.Finally,a perspective on future high-performance cells with low-cost gas diffusion layers is proposed.
