The present invention provides a solid oxide cell including a fuel electrode layer, an electrolyte layer and a cathode layer, wherein the solid oxide cell comprises an anti-reaction film between the air electrode layer and the electrolyte layer, wherein the anti-reaction film is formed on the electrolyte layer, A first reaction preventive film including a sintered ceria based metal oxide not including the first reaction preventive film; And a second reaction preventive layer formed on the first reaction preventive layer, the second reaction preventive layer including a sintered metal oxide and a sintering auxiliary agent mixed and sintered, wherein the first reaction preventive layer comprises a nano powder of a ceria metal oxide, Wherein the powder is sintered, and the first reaction preventing film and the second reaction preventing film are simultaneously sintered. Thus, the efficiency and stability of the solid oxide cell can be remarkably improved by being dense, having a high interfacial bonding force, and preventing the secondary phase generation due to a chemical reaction with the electrolyte. |
