New PEACE project publication: Advancing membrane materials for AWE
Published: September 2, 2025
PEACE team members from the Institute of Engineering Thermodynamics, German Aerospace Center (DLR), contributed to and co-authored a new peer-reviewed article in Journal of Membrane Science by Elsevier which has been just published!
The article, titled “Tuning properties of PEO-functionalized ion-solvating blend membranes via PEO side chain length: Impact on alkaline water electrolysis performance” demonstrates a high-performance potential of ion-solvating-type membranes in alkaline water electrolysis (AWE).
The study introduces a polymer blend strategy to create high-performance membranes with excellent conductivity, stability, and durability under demanding electrochemical conditions. The key points of the paper are:
· Innovative Membrane Design: Novel PEO-functionalized copolymers blended with m-PBI which resulted in membranes that combine mechanical stability with high ionic conductivity.
· Promising Electrolyzer Performance: Tested membranes by DLR supported by the PEACE project outperformed the current commercial benchmarks in terms of the current density while displaying satisfying level of safety (in terms of hydrogen crossover).
The AWE-based developed membranes represent a promising pathway to improve efficiency and durability in large-scale green hydrogen production.
