摘要：

State-of-the-art nickel-based SOFC anode-supported cells are highly sensitive to reoxidation of the metal phase at the temperature of utilization. This work presents results on redox stable nickel-YSZ (yttria-stabilized zirconia) anode-supported cells, for both smaller and larger scale cells. A 55 cm(2) cell was mounted in a SOFC stack repeat element and tested over 40 full redox cycles. Performances and electrochemical impedance results of the repeat element are compared to the smaller sized cells of similar anode support structure. (C) 2010 Elsevier B.V. All rights reserved.
