中文摘要：
比较了用干法和湿法制备的微孔层（MPL）对质子交换膜燃料电池（PEMFC）输出性能的影响。结果表明干法MPL具有较湿法MPL更优的“水管理”功能。对基于干法MPL和湿法MPL的气体扩散层（GDL）分别进行了表征，包括扫描电子显微镜法（SEM）、透气率以及表面接触角。表征结果支持上述实验结论。干法MPL中PTFE质量百分含量的最优值为30％。
英文摘要：
The performance of the PEMFC single cells with dry-layer MPL and wet-layer MPL were investigated. The experiments indicate that the transport of liquid watedgas in GDL with dry-layer MPL is much better than that with wet-layer MPL, especially when the PEMFC is performed at high current densities. The surface morphology, hydrophobic characteristic of the surface and gas permeability of the GDLs with dry-layer MPL and wet-layer MPL were characterized, The results show good agreement with the experimental observations. The optimal value of PTFE content in dry-layer MPL is 30%.
