    Abstract: An interconnector (A1) for a high-temperature solid electrolyte fuel cell comprises: sintered chromium alloy formed with sintering pores, where the chromium alloy contains chromium (Cr) (greater than 90 wt.%), iron (Fe) (3-8 wt.%), aluminum (Al) (0.1-2 wt.%), optional at least one element (0.001-2 wt.%) selected from rare earth metals; and the sintering pores are at least partly filled with an oxidic compound containing Al and Cr. Independent claims are included for the following: (1) high-temperature solid electrolyte fuel cell comprising: ceramic solid electrolyte formed of stabilized zirconium oxide; and the interconnector (A1); (2) producing interconnector (A1) involving producing a powder mix from at least one of a mixed powder, partly pre-alloyed powder, and a fully pre-alloyed powder, shaping by die pressing at a pressing pressure set to 500-1000 MPa, optionally presintering at a temperature set to 700-1200[deg] C in a reducing atmosphere and optionally calibration pressing at a pressing pressure set to 500-1000 MPa, sintering at a temperature set to 1200[deg] C to solidus temperature in a reducing atmosphere, and oxidatively treating for producing the interconnector (A1).

    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 invention relates to a substrate-supported anode for a high-temperature fuel cell, comprising an at least 3-layer anode laminate (A1, A2, A3) on a metal substrate. The individual layers of the anode laminate each comprise yttrium-oxide-stabilized zirconium dioxide (YSZ) and nickel, wherein the average grain size of the nickel decreases from layer to layer with increasing distance from the substrate. The last layer of the anode laminate, which is intended for contact with the electrolyte, has a root-mean-square roughness R q , also described as average surface roughness in the context of the invention, of less than 4 µm. The overall average pore size of said layer is generally between 0.3 and 1.5 µm. In the method for producing such a substrate-supported anode for a high-temperature fuel cell, starting powders having a bimodal grain size distribution of yttrium-oxide-stabilized zirconium dioxide (YSZ) and nickel-containing powder are used at least for the first and second layers of the anode laminate. The average grain size of the nickel-containing powder used is reduced from layer to layer so that the average grain size in the last layer of the anode laminate is advantageously no greater than 0.5 µm.
