    Abstract: PROBLEM TO BE SOLVED: To provide an interconnector or an end plate for fuel cell stack, which can be manufactured by compression molding and sintering inexpensively, and which has high density and optimal homogeneity. SOLUTION: A shaped part consists of a disk-shaped or plate-shaped basic body (1) having a multiplicity of knob-like and/or ridge-like elevations (2) with a height h, and the cross-section thereof has two inclined side flanks, each of which leads, proceeding from an end contour (3) of the elevation (2), via a rounded corner portion (4) with a radius r directly or via an intermediate rectilinear portion (5) into a curved portion (6) having a radius R, the curved portion (6) merging into the surface contour (7) of the basic body (1). When the transition is started from the rectilinear portion or the rounded corner portion immediately to the curved portion, a tangent at the transition point forms an inclined angle α in a range of 95° to 135° against the surface contour, the radius R is in the range of 0.15 to 1 mm, and the height h is dimensioned so that the ratio of R:h is in a range of 0.25 to 1.

    Abstract: The invention relates to a layer structure which is formed between an interconnect and a cathode of a solid oxide fuel cell and can be used for forming a ceramic layer structure between an interconnect and a cathode. In this respect, the interconnect comprises a metal alloy containing chromium. The object of the present invention is to provide a layer structure between an interconnect and a cathode of a solid oxide fuel cell with which a good protective function (from corrosion and from chromium vaporization), a high electrical conductivity and also a good thermal expansion behavior adapted to the materials of an interconnect and of a cathode can be achieved. The layer structure in the green state is formed by a powdery spinel as well as at least one of the below-named metal oxides CuO, NiO, CoO x and MnO x as a sintering additive and at least one powdery perovskite. In this respect, chromium is not contained in any of these chemical compounds and the portion of spinel contained with the metal oxides as a sintering additive is reduced starting from the side facing the interconnect up to the side facing the cathode and the portion of perovskite is reduced starting from the side facing the cathode in the direction of the side facing the interconnect.

    Abstract: The invention describes a shaped part, in particular an interconnector or an end plate for a fuel cell stack, which is produced by pressing and sintering a pulverulent starting material. The shaped part consists of a disc-shaped or plate-shaped basic body -1-having a multiplicity of knob-like and/or ridge-like elevations -2- with a height h. In cross section, each elevation -2- has two inclined side flanks which lead, proceeding from an end contour -3- of the elevation -2-, via rounded corner portions -4-, -4'- with a radius r or r' directly or via intermediate rectilinear portions -5-, -5'- into curved portions -6-, -6'- with a radius R or R', which in turn merge into the surface contour -7-, -7'- of the basic body -1-. The rectilinear portions -5-, -5'-or, in the case of a direct transition of the rounded corner portions -4-, -4'- into the curved portions -6-, -6'-, the tangents at the point of the transition, have an angle of inclination a or a' with respect to the surface contour -7-, -7'- in the range of 95° to 135°. According to the invention, the radius R or R' is in the range of 0.15 to 1 mm and the height h is dimensioned such that the ratio R: h or R' : h is in a range of 0.25 to 1.

    Abstract: The substrate-supported anode for a high-temperature fuel cell according to the invention comprises an at least three-layer anode laminate (A1, A2, A3) on a metallic substrate. Each of the individual layers of the anode laminate comprises yttria-stabilized zirconia (YSZ) and nickel, wherein the mean particle size of the nickel decreases from one layer to the next as the distance from the substrate increases. The last layer of the anode laminate, which is provided for the contact with the electrolyte, has a root mean square roughness R q, which within the scope of the invention is also referred to as mean surface roughness, of less than 4 µm. The overall mean pore size of this layer is typically between 0.3 and 1.5 pm. In the method for producing such a substrate-supported anode for a high-temperature fuel cell, starting powders having a bimodal particle size distribution of yttria-stabilized zirconia (YSZ) and nickell-containing powder are used at least for the first and second layers of the anode laminate. The mean particle size of the nickel-containing powder that is used is reduced from one layer to the next, whereby it is advantageously no more than 0.5 pm in the last layer of the anode laminate.
