摘要：

本文以具有良好亲水性的聚乳酸乙醇酸(poly-lactide-co-glycolide, PLGA)纳米纤维制备了Nafion/PLGA复合质子交换膜，其屈服强度、断裂强度和弹性模量达到10.5MPa、19MPa和147.8MPa，优于相同条件下的Nafion均质膜。Nafion/PLGA复合质子交换膜电导率达到0.053Scm-1，结构致密、单电池开路电压达到0.96V，并在100mAcm-2-900mAcm-2的欧姆极化控制区域呈现良好的性能。

The approach in this research is developing a composite proton exchange membrane with poly-lactide-co-glycolide (PLGA) fibers and perfluorosulfonic acid (PFSA, Nafion) ionomers. With the high strength and conductive PLGA fibers, the yield strength, breaking strength and elastic modulus of the Nafion/PLGA composite membrane achieved 10.5MPa、19MPa and 147.8MPa. The proton conductivity of Nafion/PLGA composite membrane was 0.053Scm-1. The single fuel cell assembled with the Nafion/PLGA composite membrane had a high open circuit voltage of 0.96 V and performed well at ohmic polarization (100mAcm-2-900mAcm-2), gave this membrane a positive further in high performance and durable PEM fuel cells.
