Design and development of branched polymers for advanced anion exchange membranes in water electrolysis for clean hydrogen production.

Anion exchange membrane water electrolysis (AEMWE) is a promising pathway for clean hydrogen production, enabling high efficiency while utilizing non-precious metal catalysts and cost-effective system components. A critical element in AEMWE systems is the anion exchange membrane (AEM), which facilitates hydroxide ion transport and maintains ionic separation between the electrodes under strongly alkaline conditions. A major challenge in advancing AEMWE technology is the development of chemically stable, highly conductive AEMs that can operate efficiently and durably in alkaline environments over extended periods.
This project focuses on the design and synthesis of branched polymer architectures tailored for high-performance AEMs in AEMWE applications. Specifically, it will investigate aryl-ether-free polymer backbones incorporating controlled branching strategies to improve hydroxide ion conductivity, ion exchange capacity, and long-term alkaline stability, while preserving membrane solubility and mechanical strength.
The resulting polymers will be processed into membranes and systematically evaluated for their electrochemical performance, water uptake, dimensional stability, and durability under alkaline conditions. Conducted in collaboration with Lund University, this project will provide advanced research training in polymer synthesis and membrane science. The outcomes are expected to support the development of next-generation AEM materials, contributing to the broader transition toward efficient, cost-effective, and scalable clean hydrogen production.
