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 disc-shaped or plate-shaped basic body with a multiplicity of knob-like and/or ridge-like elevations with a height h. In cross section, 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 α or α′ with respect to the surface contour, in the range of 95° to 135°. 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.
