FABRICATION METHOD FOR ANODE OF SOLID OXIDE FUEL CELL

摘要

Provided are a negative electrode material for a solid oxide fuel cell which is excellent in reaction activity and heat cycle stability, and a method for preparing the negative electrode material. The negative electrode material comprises a main body which comprises nickle oxide(NiO) and stabilized zirconia in a ratio of 55:45 to 45:55; a first functional layer which comprises nickle oxide and stabilized zirconia in a ratio of 30:70 to 45:55 and is coated on the surface in contact with an electrolyte; and a second functional layer which comprises nickle oxide and stabilized zirconia in a ratio of 55:45 to 70:30 and is coated on the other surface. Preferably the first and second functional layers have a thickness of 5-50 micrometers, respectively, and comprise a single layer.
