Abstract

Silica mesoporous/heteropolyacid(HPA)-PVA/SSA hybrid membrane was prepared by solgel processes to make a proton conducting membrane. The method involves stabilization of HPA in inorganic-organic hybrid membrane. By adding HPA in the silica mesoporous-PVA/SSA matrix, the membrane showed high proton conductivities of 10-3 S/cm at room temperature. Methanol crossover was decreased with increasing the contents of mesoporous material. This simple method can be applied to make a proton conducting membrane involving mesoporous structure.
