Abstract: Polymer electrolyte membranes (PEMs) composed of poly(vinyl alcohol) (PVA), modified PVA polyanion containing 2 mol% of 2-methyl-1-propanesulfonic acid (AMPS) groups as a copolymer and sulfosuccinic acid (SSA) were prepared by solution blending. The PEMs of various AMPS and SSA contents (C AMPS and C SSA , respectively) and crosslinking conditions were prepared to determine the effect of sulfonic acid group contents and crosslinking conditions on PEM properties. Proton conductivity and methanol barrier propert… Show more
