Julie GUEHL

My PhD project, supervised by Pr. Elena SAVINOVA (ICPEES), Dr. Eric SIBERT (LEPMI), Dr. Tristan ASSET (ICPEES) and Dr. Alexandr Oshchepkov (ICPEES) aims to developp cathode materials for an anion exchange membrane electrolyzer for large-scale green hydrogen production. The project focuses on developing nickel-based materials and Ni/metal oxide composites, studied at the level of model surfaces and nanoparticles, and optimized for production as electrodes of 25-30 cm². These electrodes must maintain their performance under operating conditions, be compatible with other components of the electrolyzer (e.g., membrane, ionomer, etc.), and function efficiently in the presence of diluted alkaline salt electrolytes.
