Abstract: An interconnector-electrochemical reaction unit cell composite body including an electrochemical reaction unit cell, and an interconnector which has a first through hole defining a fuel gas flow channel and which is disposed on the side toward an anode of the electrochemical reaction unit cell. The interconnector includes a coating forming a first surface of the interconnector opposite the anode. The coating includes a first coating and a second coating a having reduction resistance higher than that of the first coating. The first coating forms a first surface region which is a portion of the first surface of the interconnector and which is located away from the first through hole. The second coating forms a second surface region which is a portion of the first surface of the interconnector, which surrounds the first through hole, and which is located between the first coating and the first through hole.

Abstract: A fuel cell with separator includes a fuel cell body having a cathode, an anode, and a solid electrolyte layer disposed between the cathode and the anode; a plate-like metal separator having first and second main surfaces and an opening which opens at the first and second main surfaces; a joint formed of an Ag-containing brazing filler metal and adapted to join the fuel cell body and the first main surface of the metal separator; and a seal formed of a glass-containing sealing material and disposed closer to the opening than is the joint, the seal being located between the first main surface and the fuel cell body and extending along the entire perimeter of the opening.
