Award: HI ERN doctoral student receives prize for best presentation
Milazzo (Italy), July 3, 2024 - PhD student Moritz Geuß was awarded the "Best Oral Presentation Award" at the HYCELTEC 2024 symposium.
In his presentation entitled "Iridium dissolution at water-electrolysis-relevant operational conditions: A gas-diffusion electrode study", he presented the quantification of iridium dissolution using a gas diffusion electrode (GDE) setup.
Moritz Geuß is investigating whether a GDE half-cell setup can be used to quantify the dissolution of iridium from real catalyst layers under proton exchange membrane water electrolyzer (PEMWE) conditions. This should support the development of more stable catalyst layers and thus long-life, low-loaded electrolyzers. While similar trends in catalyst stability are observed in full-cell and half-cell structures, there are currently still differences in the stability actually observed.
Moritz Geuß studied chemical and bioengineering at the Technical Faculty of the Friedrich-Alexander- University Erlangen-Nürnberg (FAU). After completing his master's thesis, he has been a PhD student in the research group "Electrochemical Energy Conversion" under the supervision of Dr. Serhiy Cherevko since March 2021.
