Abstract Scope Hydrogen storage technologies are becoming increasingly feasible to meet future energy demands using renewable and clean energy technologies. Solid oxide electrolysis cells (SOECs) are highlighted as a promising renewable energy technology for hydrogen production and energy storage. While many advancements in electrode materials have been made to improve cell performance and stability for long term operation, SOECs still face challenges to extend cell life required for commercialization. In this study, infiltration of nanocatalyst gadolinium-doped ceria (GDC) into the fuel electrode is investigated as an option to further improve cell performance by mitigating Ni coarsening, a known degradation mode of the fuel electrodes, and adding robust reaction sites to improve cell performance during long-term operation. Baseline and GDC-infiltrated cells are compared after 500hrs of SOEC operation using quantitative electrochemical and microstructural analyses. The GDC-infiltrated electrode demonstrates mitigated loss of reaction sites and significantly less performance degradation over the testing period.
