摘要：

In order to further enhance the proton conductivity of proton exchange membrane, sulfonated poly (aryle ether ketone sulfone)/polyvinyl alcohol(PVA) composite membranes with different contents of PVA were prepared using solution blend mixed method. It is found that the introduction of PVA can improve the thermal stability, composite membrane water absorption and water retention capability of this membrane. Water uptake and proton conductivity increase with the PVA content increasing. The proton conductivities of all composite membrane exceedes 0.07 S/cm at 80°C, which meets with the requirement of proton exchange membrane fuel cells (PEMFC) under the elevated temperature operation.
