Stability of Nickel/Scandia-Doped-Stabilized-Zirconia Composite Anode under High Fuel Utilization Conditions

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Stability of nickel/scandia-doped-stabilized-zirconia (Ni/ScSZ) composite anode under high pH2O condition was investigated. Electrolyte supported cell with ScSZ electrolyte and Ni/ScSZ anode was operated at 700oC for 500 h by feeding mixture of H2/H2O/N2as a fuel. Under 10%H2-40%H2O-50%N2, Sc diffused out of the ScSZ grain and dissolved into the adjacent Ni phase. Condensation of Sc in the Ni grain was enhanced by the application of current density of 0.5
