| Abstract Scope |
Solid oxide cells (SOCs) are regarded as promising energy conversion and storage systems that operate efficiently as both a fuel cell (FC) and an electrolysis cell (EC). However, air electrode barrier layer detachment and microstructural degradation of the fuel electrode are known to be major factors affecting their durability. In this research, stable and robust SOCs with air electrode barrier layers were manufactured, enabling a fuel electrode-focused degradation study to be performed. Cells with non-infiltrated and GDC-infiltrated fuel electrodes were operated under EC and reversible (alternating between FC and EC) conditions. To evaluate the overpotentials, I-V curves and EIS data were obtained under various gas conditions and fitted to extract the individual components of the overpotential. Employing this approach and combining with microstructural characterization, the degradation of the fuel electrode is tracked, and the positive impact of GDC infiltration into the fuel electrode is evaluated. |
