摘要：

Composite membranes were prepared by (a) infiltrating NAFION(TM) with SiO2-P2O5-ZrO2 sol, and (b) recasting a film using NAFION(TM) solution containing SiO2-P2O5-ZrO2 sol. The membranes were characterized by Differential Thermal Analysis and ac-impedance spectroscopy as a function of relative humidity. The influences of the heat treatment (80degreesC-150degreesC) and cleaning on the electrical properties were investigated. The incorporation of SiO2-P2O5-ZrO2 gels into NAFION(TM) lead to improvements in its thermal stability and proton conductivity.
