The possibility of performance recovery of the sulfurated Ni-yttria stabilized zirconia anode by shifting the anode potential to the stable region, in which nickel exists as metal, is investigated. The effect of controlling the potential of the anode to the stable region to suppress the generation of nickel sulfide is also revealed. The surface of Ni particle reacts with sulfur to form Ni3S2 in a low temperature region; however, the nickel is reduced to metallic by shifting the electrode potential to -1.9 V vs reference electrode exposed to O2. When the potential of the Ni-based anode is maintained at the value of ≤ -1.9 V vs the reference electrode potential, the sulfidation of nickel is inhibited.
