A manufacturing method of a molten carbonate fuel cell (MCFC) anode includes the steps of: forming a Ni coating solution for coating a surface of alumina powder by mixing nickel acetate and ethanol in a predetermined ratio, adding distilled water to the mixture in a predetermined ratio and refluxing the resultant; coating a pre-treated surface of alumina powder with the Ni coating solution; mixing a pure Ni powder and Ni-coated alumina powder obtained in the Ni coating step, and then forming a green sheet of an electrode from the mixture of pure Ni powder and Ni-coated alumina powder; and drying and sintering the electrode in a reducing atmosphere. Thus, various problems in manufacturing conventional anodes of Ni-metal alloy powder can be solved, and an anode for an MCFC having greatly enhanced creep resistance and electrode performance can be obtained.
