Abstract

Polymer electrolyte membranes (PEM) prepared by radiation-induced graft copolymerization are investigated. For this purpose, commercial poly(ethylene-alt-tetrafluoroethylene) (ETFE) films were activated by electron beam treatment and subsequently grafted with the monomers glycidyl methacrylate (GMA), hydroxyethyl methacrylate (HEMA) and ,'-methylenebis(acrylamide) (MBAA) as crosslinker. The target is to achieve a high degree of grafting () and high proton conductivity. To evaluate the electrochemical performance, the PEMs were tested in a fuel cell and in a vanadium redox-flow battery (VRFB). High power densities of 134 mW∙cm and 474 mW∙cm were observed, respectively.

摘要

研究了通过辐射诱导接枝共聚制备的聚合物电解质膜（PEM）。为此，商业聚（乙烯-交替-四氟乙烯）（ETFE）薄膜通过电子束处理进行活化，随后用甲基丙烯酸缩水甘油酯（GMA）、甲基丙烯酸羟乙酯（HEMA）和作为交联剂的N,N'-亚甲基双丙烯酰胺（MBAA）单体进行接枝。目标是实现高接枝度（）和高质子传导率。为了评估电化学性能，在燃料电池和钒氧化还原液流电池（VRFB）中对PEM进行了测试。分别观察到134 mW∙cm和474 mW∙cm的高功率密度。
