The commercialization of anion-exchange membrane water electrolysis (AEMWE) is important to produce low-cost and high-purity hydrogen. However, water electrolysis with an anion-exchange membrane (AEM) has limitations such as its poor stability and ionic conductivity, leading to low durability and performance of AEMWE. In this study, we developed superior-performance and stable AEMWE by employing an AEM without aryl-ether backbone structure. To achieve superior -performance and durable AEMWE, the effect of various parameters that is suitable for the adapted AEM was estimated. As a result, the AEM adapted in this work showed much better and was more durable than the conventional AEM (FAA-3). Moreover, it exhibited high efficiency under pure water feeding conditions. These results were contributed to high-efficient and durable AEM caused by its absence of aryl-ether backbone. This work suggests the potential use of polyphenylene structure as aryl-ether free backbone of AEM on AEMWE under alkaline solution and/or pure water condition.
