| 제목 | Synthesis and characterization of poly(phenylene)-based anion exchange membrane materials with oligomeric chain extender for fuel cell and water elecyrolysis. |
| 초록 | Anion exchange membranes (AEM) have been consideredas essential materials for electrochemical application such as anion exchangemembrane fuel cell (AEMFC) and water electrolysis. For advancement in highperformance of AEMFC, anion exchange membrane (AEM) with excellent stabilityand high ion conductivity is required. In this study, we report a series of oligomeric chainextender-derived AEMs (QPP-b-PSK-w-TMA) with increased molecular weights. TheQPP-b-PSK-w-TMA membranes showed excellent polymer main-chain stability as wellas outstanding hydroxide conductivity, 129 mS cm–1 at 80 °C, which is 1.6 timeshigher than that of FAA-3, moreover, the QPP-b-PSK-w-TMA also exhibitedremarkable thermally stabile rheological property originated from main chainstructure. Moreover, single cell performance of AEMFC and AEMWE with QPP-b-PSK-w-TMA membrane was evaluated. |
