An electrolyte membranes at high temperature/low humidity is a demand for the proton exchange membrane fuel cells (PEMFCs). In this work, we prepared hybrid membranes, which have novel glass content in the hydrophilic-channels of sulfonated poly(arylene ether sulfone) (SPAES) by in-situ sol-gel synthesis of various funtional silane. The effect of silicate from funtional silane content on the proton conductivity, water uptake of the hybrid membranes under high temperature and low humidity was quantitatively identified. The silicate content contributed to the enhancement of not only proton conductivity, but also water retention ability for PEMFCs operation. |
