NICKEL OXIDE-STABILIZED ZIRCONIA COMPOSITE OXIDE, PROCESS FOR PRODUCTION THEREOF, AND ANODE FOR SOLID OXIDE TYPE FUEL CELL COMPRISING THE COMPOSITE OXIDE

The present invention relates to a nickel oxide-stabilized zirconia composite in which nickel oxide is dispersed uniformly, a process for readily producing the composite oxide, and an anode for a solid oxide fuel cell having excellent output characteristics. More specifically, the present invention provides a nickel oxide-stabilized zirconia composite that is produced by sintering a mixture of nickel hydroxide and/or nickel carbonate and a hydroxide of stabilized zirconium.
