NOVELTY - A metallic interconnect has first (51) and second border pieces, each being shaped with internal cut-out so that an internal cavity (55) having holes (53) on opposing sides is formed. An interconnect foil is disposed between first and second border pieces. First and second wire gauzes (66) are disposed respectively in the cavities of the first and second border pieces.    USE - For series-connecting an anode surface of planar fuel cell to a cathode surface of an adjacent planar fuel cell.    ADVANTAGE - The inventive interconnect is inexpensive and simple to manufacture. It simplifies and lowers the cost of solid oxide fuel cell stacks.    DETAILED DESCRIPTION - A metallic interconnect consists of first and second border pieces, interconnect foil, and first and second metallic wire gauze. Each border piece is made of metal. It is flat and shaped with internal cut-out so that an internal cavity with wide margins on opposing sides is formed. Each margin comprises holes. The holes on the first border piece is for the passage of reducing gas, and the holes on the second border piece is for the passage of oxidizing gas. The interconnect foil comprises an electrically-conducting material with holes of reducing and oxidizing gas passages, respectively. The interconnect foil is disposed between the first and second border pieces, so that the reducing-gas passage holes of foil are in registration with the reducing-gas passage holes of first border piece and the oxidizing-gas passage holes of foil are in registration with the oxidizing-gas passage holes of second border piece. The reducing-gas passage holes of foil allow passage of reducing gas in and out of second border piece cavity, and the oxidizing-gas passage holes of foil allow passage of oxidizing gas in and out of first border piece cavity. The first and second wire gauze are respectively disposed in the cavities of first and second border pieces, so that the first wire gauze provides electrical continuity between an anode cell surface and foil surface, and the second wire gauze provides electrical continuity between a cathode cell surface and foil surface when the interconnect is in connecting relationship between the fuel cells.    An INDEPENDENT CLAIM is included for a series-connected solid oxide fuel cell stack comprising at least two cells disposed relative to each other, and at least one interconnect for providing the series-connection. Each fuel cell comprises an anode layer containing a porous mixture of electronically-conducting material and oxygen ion-conducting material, a cathode layer containing a porous mixture of electronically-conducting catalyst and oxygen ion-conducting material, and an electrolyte layer of oxygen ion-conducting material disposed between the anode and cathode layers.
