Abstract
Green hydrogen production technology has drawn much interest due to its high energy density and eco-friendly energy production of hydrogen. In particular, anion exchange membrane water electrolysis (AEMWE) have been at the core of recent research because of the low cost of hydrogen production by using a non-precious metal catalyst and non-fluorinated ion-conducting polymer electrolyte membranes. Nevertheless, the poor durability and low performance of AEMWE, due to chemical degradation of AEMs in alkaline conditions and the low diffusivity of OH-, need to be addressed for practical use of AEMWE. In this study, we developed a novel ion-conducting polymers with intermolecularly interacting groups as novel AEMs. This newly developed polymer-based AEMs, exhibited high ion conductivity and excellent alkaline stability, and showed good WE cell performance and durability when applied to AEMWE. The use of this polymer as an ionomer in AEMWE application also showed a promising result. The details of the synthesis, characterization of the new polymers, and AEMWE cell performance will be detailed.
