Abstract

Catalytic properties and degradation of Co₃O₄ infiltrated La_0.6Sr_0.4Co_0.2Fe_0.8O₃/Ce₀. Gd_0.1O₂ (LSCF/CGO) cathode with Ag current collectors have been studied in this work. By controlling the infiltration sequence and the distribution of Co₃O₄ nanoparticles, we were able to distinguish the aging effects of LSCF/CGO composite cathode and Ag current collector contributed to the cathode's performance. It was confirmed that the stability of the infiltrated cells was influenced by the stability of both LSCF/CGO cathode and the Ag current collector. The aging of Ag current collector was found to be a major detrimental factor of the cell degradation, significantly enlarging the ASR during aging. Such deterioration was found to be suppressed by Co₃O₄ infiltration.
