Abstract

We utilized stable Sr0.9La0.1TiO3 (SLT) with Ce0.9Gd0.1O2 (GDC) and (Sc2O3)0.1(CeO2)0.01(ZrO2)0.89 (SSZ) to fabricate robust anode for SSZ electrolyte-supported SOFC single cell. The anode consisted of three layers: a layer of 60wt% GDC-SLT or 40wt% SSZ-SLT as a functional layer and two layers of SLT as current conducting layers. Cathode was composed of a layer of 50wt% SSZ-LSM as a functional layer and a layer of LSM as a current conducting layer. Impregnation method has been employed to decorate nano-sized Ni and CeO2 into the ceramic anode. We measured electrochemical properties of single cells in 3%-humidified H2 at 800°C, and investigated long-term redox stability of the nano-sized catalyst impregnated ceramic anodes by fuel interruption method.
