摘　　要：燃料电池作为一种高效环保的绿色能源,有望获得重要应用.作为聚合物电解质膜燃料电池和直接甲醇燃料电池的核心部件,质子交换膜的研制是该领域的热点.针对目前具有产业化规模的Nation膜所表现的使用温度低及阻醇性差等缺点，开发能够替代Nation的下一代高性能质子交换膜备受关注[1]．A naphthylene-containing sulfonated polyaryletherketone（SPAEK） was synthesized as a matrix.A polyazomethine having naphthylene,ether and ketone linkages（PAM） was selected as a molecular-enhanced component.Aimed at improving the properties,a ternary-composite membrane was constructed by incorporating sulfonic acid-functionalized polysilsesquioxane through a sol-gel processing.The morphology of the membranes was studied by SEM.Compared with plain SPAEK and SPAEK/PAM blend,the ternary-composite membranes show higher proton conductivity and selectivity.
