? 2022 Elsevier B.V.In this study, even if excess electrolyte is injected, stable performance is maintained because SDC (Sm0.2Ce0.8O2?δ) coated on the surface of the anode induces electrolyte redistribution. In addition, the SDC coating is intended to increase the performance and lifetime of the cell by improving the thermal stability of the anode at high temperatures. An SDC-coated Ni-based anode is manufactured by dip-coating SDC (Sm0.2Ce0.8O2 ?δ) sol on a Ni-based anode. As a result of operating the cell in which excess electrolyte (pore filling ratio 115–120%) is injected, the “flooding” phenomenon caused by excessive electrolyte injection is suppressed within 72 h of cell operation, and the cell performance maintains a high performance of 0.72 V at 150 mA/cm2. In addition, the thermal stability of the Ni-based anode is increased due to the SDC coating, and stable performance is maintained for more than 1000 h of operation.
