Patent ID: 7632586

Claim:
A positive electrode-electrolyte-negative electrode-assembly for a solid oxide fuel cell (SOFC PEN) with a cathode, said cathode comprising a porous cathode layer and an active cathode layer, with an anode, said anode comprising three distinct continuous layers, each of these layers forming a single, continuous structure, said anode layers comprising an active anode layer, an anode support layer, and an anode collector layer, said anode support layer constituting the mechanical support of the PEN, and with at least one electrolyte layer, said electrolyte layer being placed between said active anode and cathode layers, wherein said anode collector layer covers the rear face of the anode support layer, and wherein the anode collector layer presents, on its rear face which is designed to come into contact with an interconnecting plate, a raised structure which is chosen so as to form gas circulation channels with said interconnecting plate, and wherein said cathode also has, on its rear face which is designed to come into contact with an interconnecting plate a raised structure which is chosen so as to form gas circulation channels with said interconnecting plate, and in that the raised structures of the anode and of the cathode each comprise a plurality of prominent bumps which are spaced apart from one another, wherein summit surfaces of the bumps of the anode are substantially coplanar and parallel to summit surfaces of the bumps of the cathode, the latter likewise being coplanar with one another.
