Abstract
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°.
