摘要： A metal plate-bonded single fuel cell unit according to one aspect of the present invention includes a single cell element having a solid electrolyte and fuel and air electrodes disposed on opposite sides of the solid electrolyte and a metal plate bonded by a brazing material to the single cell element. The metal plate contains Ti and Al and has an Al-Ti-containing oxide layer present on a surface of the metal plate, an Al oxide film present on a surface of the Al-Ti-containing oxide layer and a Ti-containing phase apart from a part of a surface of the Al oxide film in contact with the brazing material while being present on a remaining part of the surface of the Al oxide film. The metal plate-bonded single fuel cell unit has a Ti reaction phase formed at an interface between the solid electrolyte and the brazing material.
