This work presents results on different anode supports fabricated by tape casting. Three compositions are prepared, as the outcome of a preceding design of experiment approach. The NiO proportion is 40, 50 and 60 wt% of the anode composite.RedOx cyclingSOFC reoxidationSolid oxide fuel cellsNi-YSZ anode supportCermet electrical conductivityDegradationDegradationConductivityCompositesMechanismsNiDesign of experiment approach applied to reducing and oxidizing tolerance of anode supported solid oxide fuel cell.
