Abstract

Abstract: In order to enhance operating temperature of proton exchange membrane fuel cell (PEMFC), sulfonated poly(aryle ether ketone sulfone)/ZrO2 composite membranes with different contents of ZrO2 were prepared by sol-blend mixed method in this paper. Infrared spectra showed that the Zr-O-Zr absorption peaks existed in composite membrane. SEM photos show ZrO2 nano-inorganic particles uniformly dispersed in SPAEKS polymer matrix. It was found that the introduction of nano-particles ZrO2 improved the thermal stability, water uptake and proton conductivity. The methanol permeability coefficient (5.6×10-7cm2/s) of SPAEKS/ZrO2-10% composite membrane was lower than that of SPAEKS film (6.7×10-7 cm2/s) at 80 oC. The proton conductivities of all composite membrane exceeded 0.08 S/cm at 80 oC, which meet with the requirement of PEMFC at elevated temperature operation. The SPAEKS/ZrO2 composite membranes showed good potential for the usage in high temperature PEMFC.
