质子交换膜燃料电池气体扩散层的耐久性研究

Study on Gas Diffusion Layer Durability of PEM Fuel Cell

对质子交换膜燃料电池（PEMFC）用气体扩散层（Gas Diffusion Layer，GDL）的耐久性问题进行了评述，分析了扩散层老化的原因，并对GDL耐久性的实验研究方法度表征手段进行了总结，最后对GDL的耐久性研究进行了展望。

The gas diffusion layer （GDL） durability of proton exchange membrane fuel cell （PEMFC） was reviewed. The testing methods and the characterization of the durability of GDL were summarized in this paper. The degradation mechanisms of GDL were analyzed through discussion. The research trends of the GDL were proposed as well.
