Abstract

Water Electrolyzers In article number 2501038, Chiho Kim, Sung Mook Choi, Taiho Park, and co-workers developed a poly(fluorene)-based anion exchange membrane (AEM) for water electrolyzer (WE). The AEM with a simple structure and an interstitial alkyl chain exhibits superior hydroxide conductivity, excellent mechanical properties, and exceptional alkaline stability, demonstrating remarkable long-term durability of AEMWE.
