Abstract

A new type of Ni-free anode material based on Co0.5Fe0.5 + SDC (Sm0.2Ce0.8O1.9) was identified and evaluated using the La0.8Sr0.2Ga0.83Mg0.17O3 (LSGM) electrolyte-supported cells. The maximum power densities with humidified hydrogen at 800 °C using Au mesh and Pt mesh as anode current collector were 1.07 and 1.20 W cm-2, respectively, which were comparable to that of the cell with the Ni + SDC anode. The cell with the new anode exhibited reasonable performance stability at 800 °C in hydrogen fuel; furthermore, no noticeable change in cell performance with the Co0.5Fe0.5 alloy anode was observed upon ordering reaction in the alloy to form the ordered α′ phase at 650 °C. © 2008 Elsevier B.V.
