Alkaline Stability of Anion-Exchange Membranes. [PDF]

open access: yesACS Appl Energy Mater, 2023
Recently, the development of durable anion-exchange membrane fuel cells (AEMFCs) has increased in intensity due to their potential to use low-cost, sustainable components. However, the decomposition of the quaternary ammonium (QA) cationic groups in the anion-exchange membranes (AEMs) during cell operation is still a major challenge.
