Abstract

Polymer electrolyte membrane (PEM) is pivotal in proton exchange membrane fuel cells (PEMFCs) with enhanced power performances. We reported a sulfonated (poly ether sulfone) (SPES) and sulfonated polyvinylidene fluoride-co-hexafluoro propylene (SPVdF-HFP) blend membrane for the PEMFC. We fabricated the SPES/SPVdF-HFP blend membrane via a simple solvent-casting method with 10 or 20% of SPVdF-HFP. It exhibited enhanced proton conductivity and was assigned to the synergism between SPES and SPVdF-HFP. FE-SEM images of composite membrane revealed the effectual dispersion of SPVdF-HFP in the SPES matrix, which may offer an extend networks for facile proton conduction. Moreover, integration of SPVdF-HFP effectively increased the power density of blend membrane i.e., 262.78 mW/cm2, it was higher by 1.51 fold compared to bare SPES membrane (173.67 mW/cm2).
