Abstract: Proton exchange membrane with interconnected H+-transfer channels in submicron scale has been synthesized by means of pore filling polymerization. Polysulfone (PSU) membrane containing densely distributed pores is synthesized using the phase inversion approach. The membrane is then filled up with a designed formula consisting of monomers (e.g. 2-acrylamido-2- methylpropane sulphonic acid and N,N′-Methylenebisacrylamide) and a binary solvent. It is undertaken through solution diffusion of the monomer formula into the pores impregnated with the bore liquid. When the PSU matrix loaded with monomers is subjected to polymerization, a uniform distribution of interconnected H+-transfer channels is realized. This special membrane structure gives rise to a maximum ionic exchange capacity of 2.43 meq/g and the highest proton conductivity of 0.2 S/cm. Compared to the commercial Nafion® membrane, the pore-filled membrane significantly enhances the power output of H2-PEM fuel cell. © 2012 Materials Research Society.
