    摘要： The substrate-supported anode for a high-temperature fuel cell comprises an at least three-layer anode laminate on a metallic substrate. Each of the layers of the anode laminate comprises yttria-stabilized zirconia 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 contact with the electrolyte, has a root mean square roughness of less than 4 μm. The overall mean pore size of this layer is typically between 0.3 and 1.5 μm. Starting powders having a bimodal particle size distribution of yttria-stabilized zirconia and nickel-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 is reduced from one layer to the next, whereby it is advantageously no more than 0.5 μm in the last layer of the anode laminate.

    摘要： A shaped part that is particularly suited as an interconnector or an end plate for a fuel cell stack, is produced by pressing and sintering a pulverulent starting material. The shaped part has a basic body with a multiplicity of knob-like and/or ridge-like elevations with a height h. Each elevation has two inclined side flanks which lead, proceeding from an end contour of the elevation, via rounded corner portions, with a radius r or r′ directly or via intermediate rectilinear portions, into curved portions, with a radius R or R′, which in turn merge into the surface contour, of the basic body. The rectilinear portions, or, in the case of a direct transition of the rounded corner portions into the curved portions, the tangents at the point of the transition, have an angle of inclination relative to the surface contour, between 95° and 135°.
