Abstract:
A method for forming a molten carbonate fuel cell anode by mixing a pure Ni powder and a Ni-coated alumina powder, the method comprising the steps of:forming a Ni coating solution for coating an alumina powder by mixing nickel acetate and ethanol in a ratio of 1:7-1:15 to form a mixture, adding distilled water to the mixture in a ratio of 1:7-1:15 to form a resultant, and refluxing the resultant; pre-treating a surface of said alumina powder with a base to form a pre-treated surface of said alumina powder; coating said pre-treated surface of said alumina powder with said Ni coating solution to form Ni-coated alumina powder; mixing a pure Ni powder and said Ni-coated alumina powder to form a mixture of pure Ni powder and Ni-coated alumina powder, 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 said electrode in a reducing atmosphere.
