摘　　要：质子交换膜燃料电池(PEMFC)是一种高效的无污染装置因而受到广泛关注。然而,PEMFC仍存在成本高、稳定性差等问题,制约了PEMFC的大规模商业应用。气体扩散层是PEMFC中的重要组成部分。针对PEMFC低成本、高性能先进材料的需求,本文综述了气体扩散层基材碳纸、微孔层的改性制备、气液传输和水管理、孔结构的模拟与设计等方面的研究进展,并指出了碳纸基气体扩散层未来的发展方向。PEMFC(proton exchange membrane fuel cell)has attracted wide attention as an efficient and pollution-free device.However,there still exist some problems such as high cost and poor stability,which restrict its large-scale commercial application.Gas diffusion layer is an important part of the cell.In order to meet the demand of low cost and high performance advanced materials for PEMFC,the research progress of carbon paper base material,preparation of microporous layer,gas-liquid transfer and water management,simulation and design of pore structure are reviewed,and the future development direction of carbon paper base gas diffusion layer is pointed out.
