Abstract:
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.
