【摘要】 综述了燃料电池用各种质子交换膜(PEM)材料及其改性方法.PEM材料包括全氟磺酸型离子交换树脂、聚苯并咪唑(PBI)、聚醚醚酮(PEEK)以及各种新型聚合物、嵌段共聚物等,而将这些材料制成PEM所采用的改性方法可分为磺化、酸基络合、杂化、共混、共聚、以及辐射接枝、等离子体等改性处理.还介绍了各种PEM材料的物性特点和PEM材料改性方法及其最新PEM研究报道.更多还原

【Abstract】 Proton exchange membrane materials (PEMs) for fuel cells and their modification methods were reviewed. The PEMs include polyperfluorosulfonic ion-exchange resin, polybenzimidazole (PBI), polyetheretherketone (PEEK), and other new types of block copolymers etc. The modification methods are divided into sulfonation, acid complex, hybridization, blend, copolymerization, radiation and plasma graft method. The advances in the properties of these PEMs and their modification methods were summarized in details.更多还原
