Abstract

Novel methanol-blocking polymer electrolyte composite membranes were prepared by inserting purple membrane (PM) to the bulk phase of Nafion^® resin. Results of scanning electron microscopy (SEM) and confocal laser scanning microscopy (CLSM) analyses show that PM was well-dispersed in Nafion^® membrane. Compared with recast Nafion^®, blending PM changed the microstructure of Nafion^® membrane and significantly improved the methanol-blocking efficiency by 31.6% in maximum. With PM content of 0.3wt% in the composite, the highest membrane selectivity factor and single cell power density of 62.1mWcm^-2 were achieved. This satisfactory cell performance has given a promising prospect of Nafion^®/PM composite membranes in the application in DMFC.
