Abstract: Die Erfindung betrifft ein pulvermetallurgisches Formteil, aufweisend einen scheiben- oder plattenartigen Grundkörper (1) und eine Vielzahl von in einer Reihenrichtung (11) aneinander gereihte und hierdurch eine Reihe bildende noppen- und/oder stegförmige Erhebungen (2) mit einer Höhe (h1, h2) senkrecht zur Grundebene des Grundkörpers (1) und mit im Querschnitt jeweils zwei Seitenflanken, welche von einer in Höhenrichtung (8) äußeren Endkontur (3) der Erhebung (2) über Eckenrundungen in kurvenförmige Abschnitte mit einem Kurvenradius münden, wobei der Kurvenradius in die Oberflächenkontur (7) des Grundkörpers (1) übergeht und wobei ein gerader Flankenabschnitt der Seitenflanke oder eine im Punkt des Übergangs von der Eckenrundung in den kurvenförmigen Abschnitt liegende Tangente der Seitenflanke in einem Neigungswinkel (a1, a1'; a2, a2') zur Grundebene des Grundkörpers (1) angeordnet ist. An derselben Seite (9, 10) des Grundkörpers (1) sind mindestens zwei unterschiedliche Neigungswinkel (a1, a1'; a2, a2') vorhanden, wobei die mindestens zwei unterschiedlichen Neigungswinkel (a1, a1'; a2, a2') mindestens eine erste Geometrie (h1, r1, r1', R1, R1', a1, a1') und eine zweite Geometrie (h2, r2, r2', R2, R2' a2, a2') repräsentieren.

Abstract: 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.

Abstract: The invention relates to a powder metallurgical molded part having a disk or plate shaped main part (1) and a plurality of knob and/or ridge shaped elevations (2) which are adjacent to one another in a row direction (11) and thus form a row and which have a height (h1 h2) perpendicular to the base plane of the main part (1) each elevation having a cross section with two lateral flanks. The lateral flanks lead from an elevation (2) end contour (3) which is arranged externally in the height direction (8) into curved sections with a curve radius via rounded corner sections. The curve radius transitions into the surface contour (7) of the main part (1) and a straight flank section of the lateral flank or a lateral flank tangent that lies at the point where the rounded corner section transitions into the curved section is arranged at an inclination angle (a1 a1 ; a2 a2 ) relative to the main plane of the main part (1). At least two different inclination angles (a1 a1 ; a2 a2 ) are present on the same face (9 10) of the main part (1) the at least two different inclination angles (a1 a1 ; a2 a2 ) representing at least one first geometry (h1 r1 r1 R1 R1 a1 a1 ) and a second geometry (h2 r2 r2 R2 R2 a2 a2 ).

Abstract: The present invention relates to a powder metallurgical moulding forming an interconnector (2) or an end plate for an electrochemical cell, which moulding has a chromium content of at least 80% by weight, a plate-like basic shape and (a) flow ffeld(s) (6) with structuring(s) (5) formed on one or both of the main faces (4) of the moulding. A ratio of the maximum diameter Dmax of the Moulding, measured along the main face (4), to a minimum thickness drain of a core region of the moulding which extends along the flow field/fields (6) and is not affected by the structuring(s) (5) is in the range 140 Dmax/dmin 350.

Abstract: A powder metallurgical molded part includes a disk or plate-like main body and a row of knob-shaped and/or ridge-shaped elevations in a row direction having a height perpendicular to a main plane of the main body and a cross section with side flanks leading from an outer end contour in height direction of the elevation via rounded corner portions into curved portions with a curve radius. The curve radius merges into the surface contour of the main body and a rectilinear flank portion or tangent of the side flank lying at the point where the rounded corner portion merges into the curved portion is disposed at an angle of inclination to the main plane. At least two different angles of inclination are on the same side of the main body and the at least two different angles of inclination represent at least first and second geometries.

Abstract: The invention relates to a powder metallurgical molded part having a disk- or plate-shaped main part (1) and a plurality of knob- and/or ridge-shaped elevations (2) which are adjacent to one another in a row direction (11) and thus form a row and which have a height (h1, h2) perpendicular to the base plane of the main part (1), each elevation having a cross-section with two lateral flanks. The lateral flanks lead from an elevation (2) end contour (3), which is arranged externally in the height direction (8), into curved sections with a curve radius via rounded corner sections. The curve radius transitions into the surface contour (7) of the main part (1), and a straight flank section of the lateral flank or a lateral flank tangent that lies at the point where the rounded corner section transitions into the curved section is arranged at an inclination angle (a1, a1'; a2, a2') relative to the main plane of the main part (1). At least two different inclination angles (a1, a1'; a2, a2') are present on the same face (9, 10) of the main part (1), the at least two different inclination angles (a1, a1'; a2, a2') representing at least one first geometry (h1, r1, r1', R1, R1', a1, a1') and a second geometry (h2, r2, r2', R2, R2', a2, a2').
