【摘要】 聚合物电解质膜在聚合物电解质膜膜燃料电池中起到至关重要的作用。与质子交换膜燃料电池(PEMFC)相比,碱性阴离子交换膜燃料电池(AEMFC)由于使用非贵金属催化剂,具有资源和成本优势而引起广泛关注。其中,制备高效离子传导化学稳定性好的碱性阴离子交换膜是具有挑战性的前沿课题之一。本文简要介绍本课题组近年来的工作,重点介绍几种杂环聚合物分子链碱性离子膜,以及基于嵌段聚合物碱性离子膜,对其设计合成、表征及其理化性能进行了较为系统的研究。同时,本文也概述我们在高温低湿聚合物质子交换膜以及基于多层复合聚合物质子膜的部分工作。更多还原

【Abstract】 Polymer electrolyte membranes are the critical components in polymer electrolyte fuel cells(PEFCs). Com pared with the PEMFC, the AEMFC takes advantage of better cathode kinetics of the oxygen reduction, i n addition, the non-precious metals such as nickel, silver or transition metal alloys could be employed inst ead of platinum, resulting in higher performance and low cost of the fuel cells. It remains one of the mo st challenging tasks to prepare highly ionic conductive and chemical stable alkaline electrolyte membranes(AEMs). In this work, an AEM based on quaternized poly(phthalazinone ether ketone)(PPEK) with dimet hylpiperazine(DMP) as both ammonium agent and cross-linker, and an AEM based on block poly(styreneethylene-butylene-styrene)(SEBS) are illustrated, respectively. Meanwhile, the preparation and properties of high temperature composite PEM are presented. The physicochemical properties and ionic conductivity of the prepared polymer electrolytes are investigated for the potential application of APEFC/PEMFC.更多还原
