Abstract
Redox-stable Sr0.9La0.1TiO3 (SLT) with Ce0.9Gd0.1O2 (GDC) and (Sc2O3)0.1(CeO2)0.01(ZrO2)0.89 (SSZ) was used to fabricate robust anodes for zirconia-based electrolyte-supported SOFCs. The anode consisted of three layers: a layer of 60wt% GDC-40wt% SLT or 40wt% SSZ-60wt% SLT as a functional layer and two layers of SLT as current conducting layers. An impregnation method has been employed to decorate nano-sized Ni and CeO2 into the ceramic anode to improve electrochemical performance and redox stability. It was found that the catalyst impregnated ceramic anode has improved redox stability compared with the conventional Ni-SSZ cermet. The incorporation of the oxide catalyst, CeO2, during co-impregnation process was found to even further improve redox stability of the anode, since CeO2 particles have a lower tendency to aggregate during redox cycling.
