Anion exchange membrane (AEM) water electrolyzers for green hydrogen production

Water electrolysis converts electrical energy into hydrogen and oxygen by splitting water molecules. Low-temperature water electrolysis is a crucial technology for a renewable energy economy, enabling efficient storage of electricity from renewable sources in the form of high-purity hydrogen. Alkaline anion exchange membrane (AEM) electrolysis combines the advantages of proton exchange membrane (PEM) electrolysis and traditional liquid-electrolyte-based electrolysis. Key benefits include the potential use of PGM-free catalysts with low cost, operation with pure water or low-concentration alkaline solutions instead of concentrated alkaline electrolytes, and compact system design with low ohmic resistance. This project aims to develop anion exchange membranes and ionomers with high alkaline stability, high hydroxide conductivity, and mechanical robustness using efficient, controlled polymerization techniques.

The selected intern will (1) conduct polymer synthesis and characterization (Schlenk line operation, glove box, NMR. GPC), (2) perform membrane fabrication and characterization (EIS, mechanical tests) and (3) collaborate within the group to evaluate the materials in electrolyzers. Through the internship, the candidate will gain hands-on experience in chemistry and electrochemistry, develop independent research skills, and enhance critical thinking for innovative problem-solving. Regular discussions will be arranged with the PI and one final written report is required.
