PROBLEM TO BE SOLVED: To provide a method for forming a reactive barrier layer on an yttrium-stabilized zirconia (YSZ) electrolyte, in consideration that there exists a need for a reactive barrier layer having excellent characteristics.SOLUTION: There is provided a solid oxide fuel cell (SOFC) or SOFC sub-component which includes a YSZ solid oxide electrolyte layer (10), a LSCF cathode layer (14) and a mixed phase layer (18) disposed between the electrolyte layer and the cathode layer and containing at least zirconia and ceria, while the cathode layer is directly in contact with the mixed phase layer and ceria is not present other than in the mixed phase layer, in between the cathode layer and the electrolyte layer. A method for manufacturing a SOFC or sub-component includes the steps of: forming a ceria layer on an electrolyte layer; heating the electrolyte layer and the ceria layer to form a mixed phase layer; and removing excessive ceria from a surface of the mixed phase layer before applying the cathode layer. |
