摘　　要：质子交换膜燃料电池(PEMFC)作为一种清洁、高效的氢能源利用手段,是目前人类应对资源短缺、环境污染问题的重要途径,其关键部件质子交换膜(聚合物电解质膜)则是目前研究的热点。多面体低聚倍半硅氧烷(POSS)纳米粒子由于其热稳定性好、易于功能化等特点近年来应用于改性质子交换膜,显著改善提高了膜材料的力学性能和质子传导等性能而引起了较多关注。文中综述了POSS在燃料电池质子交换膜中的应用进展,重点阐述了POSS的作用机理,为有机/无机复合质子交换膜的研发与应用提供参考。Development of polymer electrolyte fuel cells （PEMFCs） is recognized as an efficient way to eliminate the energy crisis and environmental pollution issues due to its cleanness and high utilization efficiency of hydrogen. As the key components of proton exchange membrane polymer, electrolyte membrane is a hot research topic. Due to the thermal stability and easy functionalization, polyhedral oligomeric silsesquioxane （POSS） is widely used as filler to enhance the mechanical property and proton conductivity of the hybrid membrane. In this work, the progress in the utilization of POSS in polymer electrolyte membrane was reviewed and the mechanism of enhancements in mechanical property and proton conductivity by POSS was illustrated. This review offers useful information for the design and application of hybrid membrane.
