Materials - Hydrogen technology

The Hydrogen research group focuses on the production of green hydrogen via PEM electrolysis. We investigate novel catalyst materials fabricated using thin-film technologies and how they can be integrated into PEM electrolysis cells. Thin-film methods are also used to create corrosion protection coatings and layers that improve electrical contact between adjacent cell components.

PEM electrolysis with optimized catalysts

The goal in developing new catalyst materials is to reduce or replace expensive materials such as iridium, which is typically used in industrial electrolyzers, while maintaining or increasing cell efficiency. We apply thin-film deposition methods such as magnetron sputtering, including reactive and/or co-sputtering processes. To evaluate the catalysts, ISFH provides extensive material characterization capabilities, along with electrochemical analysis in three-electrode setups and under real operating conditions in our PEM single-cell test stands.

Additional focus: ammonia fuel cells

In addition to PEM electrolysis catalysts, we are developing advanced catalyst materials for the direct use of ammonia in low-temperature direct ammonia fuel cells. Our approach relies on innovative materials science to maximize efficiency and durability.

Durability & efficiency through materials development

Another key focus is the development of corrosion protection coatings for components used in water electrolysis cells. This is essential to ensure the lifetime and reliability of components in hydrogen-based energy systems.

Our advanced PEM electrolysis test stands allow detailed evaluation of modified and improved cell components in single-cell configurations. Through extensive materials research and optical analysis, we contribute to advancing the technology from lab scale toward industrial application.
