Abstract: A fuel battery and a fuel cell stack, the fuel battery including: a fuel cell that generates electric power through a power generating reaction of reactant gases and includes a solid electrolyte layer having a first main surface and a second main surface, a first electrode disposed on the first main surface and serving as one of a cathode and an anode, and a second electrode disposed on the second main surface and serving as the other one of the cathode and the anode; an interconnector disposed so as to face the first electrode; and a current collecting member that electrically connects the first electrode to the interconnector. The first electrode includes: an inner portion connected to the current collecting member; and an outer portion disposed outward of the current collecting member and having a height larger than the height of the inner portion.

Abstract: 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.

Abstract: A separator-fitted single fuel cell having a single fuel cell, a plate-shaped metallic separator that includes a through hole, and a joint portion that joins the single fuel cell to the metallic separator and is made of a brazing material containing Ag. The joint portion includes a protruding portion that protrudes from a gap between the single fuel cell and the first main surface of the metallic separator toward the through hole. The protruding portion is lower than the second main surface as viewed from the single fuel cell. The single fuel cell includes a sealing portion that is disposed along the entire circumference of the through hole of the metallic separator, covers the protruding portion and a part of the second main surface, and is made of a sealing material containing glass.
