To bring hydrogen technologies closer to large-scale deployment, researchers need to understand how different electrolyser components behave under realistic operating conditions. In this study, the HYScale team investigated the impact of cell design, operating pressure and electrolyte management on the performance and durability of anion exchange membrane water electrolysers (AEMWEs).
After testing different material combinations and operating conditions, the researchers identified configurations that improved long-term stability and reduced degradation during operation.
Key findings:
- Nickel-based components showed better long-term stability than stainless-steel alternatives
- Electrolyte concentration strongly influenced degradation rates
- Very low electrolyte flow rates reduced performance, especially at high current densities
- Operating conditions are as important as material selection for long-term durability
- The results provide practical guidance for industrial AEM electrolyser operation
