Abstract: A powder metallurgical molding forms an interconnector or an end plate for an electrochemical cell. The molding has a chromium content of at least 80% by weight, a basic shape of a plate and one or more flow fields with structuring formed on one or both of the main faces of the molding. A ratio of a maximum diameter Dmax of the molding, measured along the main face, to a minimum thickness dmin of a core region of the molding which extends along the flow field or fields and is not affected by the structuring lies in a range of 140≦Dmax/dmin≦350.

Abstract: A powder metallurgical component has a chromium content of at least 80% by weight and pores and/or oxide inclusions which are present in the component. The number per unit area of a sum of pores and oxide inclusions at a cut surface through the component in at least one region is at least 10,000 per mm2.

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, 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. A ratio of the radius R:h or R′:h ranges from 0.25, or preferably from 0.5 to 1.
