| Abstract Scope |
Hydrogen storage has become important in meeting future energy demands using renewable and clean energy technologies. Solid oxide electrolysis cells (SOECs) provide a promising option for hydrogen production and energy storage with high efficiency. While many advancements have been made to improve cell performance and stability for long term operation, SOECs still face challenges to extend cell life. Long term stable operation is necessary for commercialization of SOECs. This study investigates infiltration of the fuel electrode using the nanocatalyst gadolinium-doped ceria (GDC) as an option to further improve cell performance by mitigating Ni coarsening, a known degradation mode of the fuel electrodes, as well as adding robust reaction sites to improve cell performance for longer term operation. Quantitative microstructural analysis is performed on baseline and GDC-infiltrated cells after 500hrs of SOEC operation. The GDC-infiltrated electrode demonstrates mitigated loss of reaction sites and significantly less performance degradation over the testing period. |
