Solid oxide fuel cell and method for producing solid oxide fuel cell

A method for producing a solid oxide fuel cell, comprising:

• a laminating step of laminating a plurality of power generation cells in a thickness direction via an interconnector, wherein:
• the power generation cells each include a solid electrolyte plate, an anode electrode disposed on one surface of the solid electrolyte plate, an anode support layer configured to support the anode electrode, a cathode electrode disposed on the other surface of the solid electrolyte plate, and a cathode support layer configured to support the cathode electrode,
• the interconnector is configured to electrically connect the anode support layer of one of the adjacent power generation cells and the cathode support layer of the other one of the adjacent power generation cells,
• the anode support layer and the cathode support layer are made of ferritic stainless steel,
• the interconnector is made of ferritic stainless steel containing aluminum, and
• a pre-oxidation step of performing an oxidation treatment on the interconnector is performed before the laminating step.
