Abstract
Anion exchange membrane water electrolysis (AEMWE) is a promising technology for producing green hydrogen using renewable electricity, without requiring precious-metal catalysts or highly concentrated alkaline solutions. However, conventional AEMWE systems still exhibit lower performance than other water electrolysis technologies because of the limited anion conductivity and insufficient alkaline stability of anion exchange membranes (AEMs). Therefore, there is a strong demand for anion-conductive polymers that provide high anion conductivity while maintaining excellent stability under strongly alkaline conditions.
In this study, a trimethylammonium-substituted poly(fluorene)-based anion-conductive polymer (TMA-PF) was designed and synthesized. The electrolyte properties of AEMs prepared from TMA-PF were evaluated and found to exhibit higher anion conductivity and alkaline stability than those of conventional AEMs. In addition, anion transport in TMA-PF was analyzed using all-atom molecular dynamics simulations. The AEMWE performance of membrane electrode assemblies employing TMA-PF as both the AEM and the anion exchange ionomer (AEI) will also be presented.
