摘要： 为了满足质子交换膜燃料电池在高温条件下对质子交换膜的使用要求，本文通过溶胶-凝胶法制备了纳米ZrO2无机粒子，并通过溶胶共混法制备了含有不同ZrO2含量的磺化聚芳醚酮砜（SPAEKS）/ZrO2复合膜。红外光谱表明复合膜中有Zr-O-Zr吸收峰。扫描电镜照片显示纳米ZrO2无机粒子能够均匀地分散在SPAEKS聚合物基体中，没有发生团聚现象。通过对复合膜的性能测试发现，纳米ZrO2无机粒子的引入提高了复合膜的热稳定性，吸水率和质子传导率。在80 ℃时，SPAEKS/ZrO2-10%复合膜的甲醇渗透系数为5.6×10-7cm2/s，低于SPAEKS膜的6.7×10-7 cm2/s。同时复合膜在80 ℃时的质子传导率都在0.08 S/cm以上，有望在高温质子交换膜燃料电池中得到应用。

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.
