AB  - Electrolyte-supported solid oxide fuel cells (SOFCs) based on 6% Sc2O3-stabilized ZrO2 (6ScSz) electrolyte and Y0.07Sr0.895TiO3 (YST) anode materials were prepared. Ni and CGO particles were infiltrated on the pore walls within the ceramic anode framework as catalysts for the anode reaction. The performance, redox stability, and time-dependent degradation of the cells were tested. Electrochemical impedance spectroscopy was used to determine the non-Ohmic losses of the cells. Possible reasons for the observed performance degradation were investigated. The mechanism of the anode reaction is also discussed based on the electrochemical results.
