Practical design guidelines for efficient AEM water electrolysis
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 […]
New self-assembling catalyst cuts iridium loading in PEM electrolysers
Iridium is one of the most expensive and scarce materials used in proton exchange membrane water electrolysers (PEMWEs). Finding ways to reduce the amount required is therefore essential for making hydrogen production more affordable. In this publication, HYScale researchers developed a new catalyst design that makes more efficient use of iridium. The catalyst layer gradually […]
A novel elastic porous transport layer Improves AEM water electrolysis performance
Most research on electrolysers focuses on catalysts and membranes. This study looked at something different: the metal layer that helps water and gases move through the cell. HYScale researchers developed a flexible nickel wire mesh that improved the contact between components inside the electrolyser and supported more efficient operation. The study showed: Up to 25% […]

Cell optimisation architecture, enabling the Green Hydrogen production
In the framework of the EFCF 2025 event, the HYScale team from CNR-ITAE prepared a conference paper on optimisation of porous transport layers and interlayers, which was successfully published on ZENODO. This study investigates how the design of electrolysers affects the efficiency and durability of flow-field-free anion exchange membrane alkaline electrolysers. Small design choices, such […]
How can hydrogen production be boosted through smart design?
As the demand for clean hydrogen energy continues to rise, researchers are working to make hydrogen production both more efficient and affordable. One promising approach is anion exchange membrane water electrolysis (AEMWE). This complex term translates into a simple process: produce hydrogen using renewable electricity without relying on critical raw materials such as costly precious […]
