A method of making and fuel electrode-supported solid oxide fuel cell (SOFC). For manufacturing the SOFC, YSZ powder containing 30 to 50 vol % of Ni is mixed with carbon powder to give a fuel electrolyte slurry which is pre-sintered, coated on a fuel electrode tube, and then the coated tube is sintered. An air electrode slurry made of (La, Sr)MnO3 powder is coated on the electrolyte-coated tube and sintered. The fuel electrode of the metal (Ni/ceramic (YSZ) cermet of the SOFC is a support and the electrolyte layer underlaying the air electrode is coated as a thin film. At about 1,000° C., the Ni components of the fuel electrode are connected to each other like a mesh, improving the fuel electrode strength while the porous fuel electrode allows the sufficient permeation of fuel gas, thereby providing a large economical profit in the production cost without degradation of fuel cell performance.
