| 摘要:质子交换膜燃料电池（PEMFC）的气体扩散层（GDL）主要由碳纸层和微孔层（MPL）组成，其直接影响了燃料电池的传质效率和性能稳定性。本文综述了超薄、柔性、集成式等新型GDL的应用形式，分别介绍了通过工艺改进和材料优化提高碳纸层和MPL水管理能力、导电性能、机械性能的研究进展，并基于GDL的应用需求，分析了通过优化孔隙结构、调节组分比例、设计接触界面等方法提升水气传输性能，以及通过不同涂层技术改善GDL耐腐蚀性与耐久性的技术策略；最后对GDL未来的发展方向进行了展望。 |
| Abstract:The gas diffusion layer (GDL) of a proton exchange membrane fuel cells (PEMFC) primarily consists of a carbon paper layer and a microporous layer (MPL)， which directly influences the mass transfer efficiency and performance stability of the fuel cell. This paper reviewed the application forms of novel GDL， including ultra-thin， flexible， and integrated types， and introduced research progress on enhancing the water management capability， conductivity， and mechanical properties of the carbon paper layer and MPL through technology improvements and material optimization. Based on the application requirements of GDL， the paper summarized technical strategies for improving water vapor transport performance by optimizing pore structure， adjusting component ratios， and designing contact interfaces， as well as enhancing corrosion resistance and durability of GDL through different coating technologies. Finally， the future development directions of GDL were outlined. |
