POWDER METALLURGICAL MOULDING

摘要

The invention relates to a powder-metallurgy molded part forming an interconnector (2) or an end plate for an electrochemical cell. Said molded part has a chromium content of at least 80 wt%, a plate-shaped basic form, and one or more flow fields (6) having one or more structures, the one or more flow fields being formed on one or both main surfaces (4) of the molded body. A ratio of the maximum diameter Dmax of the molded part measured along the main surface (4) to a minimum thickness dmin of a core region of the molded part, which core region extends along the one or more flow fields (6) and is not affected by the one or more structures (5), is in the range of 140 = Dmax/dmin = 350.
