PURPOSE: Provided is a metal interconnector for a solid oxide fuel battery which has excellent oxidation resistance and conductivity and ion-conductivity and is chemically stable against materials for anode and cathode. CONSTITUTION: The metal interconnector is produced by forming beta phase NiAl metal interconnector having a composition of NixAl(1-x), in which x is 0.45 to 0.55; and coating the surface of the beta phase NiAl metal interconnector with LMO(Lanthanum manganese oxide) having a composition of La(1-x)MnO3, in which x is 0.01 to 0.05. The LMO coating is conducted by dipping the beta phase NiAl metal interconnector in LMO coating solution, drying the coating layer in an oven at 50 to 80 deg.C, followed by cooling, and thermal treating the product at 800 deg.C to obtain LMO layer. |
