The project aims to develop novel catalysts and electrodes for the electrochemical synthesis of ammonia (NH3) at high temperature (400–650 °C), using Solid Oxide Electrolysis Cells (SOEC) and Protonic Ceramic Electrolysis Cells (PCEC). Ammonia is not only a key chemical for fertilizers, but also a promising fuel and a hydrogen carrier. Unlike the energy-intensive and carbon-heavy Haber-Bosch process, the electrochemical route allows for more sustainable production with zero CO2 emissions if powered by clean electricity. The post-doctoral fellow will contribute to the identification and shaping of catalysts (e.g. Ru/YSZ, Fe/YSZ, Mn4N/BCZY), their integration into electrodes, and the evaluation of electrochemical performance. The work combines catalysis, electrochemistry, advanced characterization, and preliminary energy assessment, in close collaboration with CEA teams and academic partners.
