Alkaline-stable anion exchange membranes: A review of synthetic approaches

Herein, we review the synthesis of cationic polymers used to promote conduction of hydroxide anions. While porous membranes doped with basic solutions and anion exchange membranes conducting non-hydroxide anions have been explored in electrodialysis, electrolysis, and water purification [8], the primary rationale for the synthesis of hydroxide

Towards the gemini cation anion exchange membranes by nucleophilic substitution reaction | Science China Materials - Home

As a critical component of alkaline fuel cells, anion exchange membranes determine the energy efficiency, output power density and the long term stability. Recently, the anion exchange membranes with gemini-cation side chains exhibit superior ion conductivity due to their good nanophase separation. However, the costly and complicated synthesis limits their scaling up and commercialization. To
