Title
(DE) VERFAHREN ZUR HERSTELLUNG EINER BIPOLARPLATTE, BIPOLARPLATTE SOWIE BRENNSTOFFZELLENSTAPEL
(EN) METHOD FOR PRODUCING A BIPOLAR PLATE, BIPOLAR PLATE AND FUEL CELL STACK
(FR) PROCÉDÉ DE FABRICATION D'UNE PLAQUE BIPOLAIRE, PLAQUE BIPOLAIRE ET PILE À COMBUSTIBLE
Abstract
(DE) Die Erfindung betrifft ein Verfahren zur Herstellung einer Bipolarplatte für einen Brennstoffzellenstapel, bei dem zwei Monopolarplatten (1, 2) gefertigt und gefügt werden. Erfindungsgemäß werden die Monopolarplatten (1, 2) unmittelbar oder mittelbar über mindestens einen zwischen den Monopolarplatten (1, 2) angeordneten, vorzugsweise stiftförmigen Körper (3) induktiv verschweißt. Die Erfindung betrifft ferner eine Bipolarplatte und einen Brennstoffzellenstapel.
(EN) The invention relates to a method for producing a bipolar plate for a fuel cell stack, in which two monopolar plates (1, 2) are manufactured and joined. According to the invention, the monopolar plates (1, 2) are directly or indirectly welded in an inductive manner via at least one, preferably pin-shaped, body (3) arranged between the monopolar plates (1, 2). The invention further relates to a bipolar plate and to a fuel cell stack.
(FR) L'invention concerne un procédé de fabrication d'une plaque bipolaire destinée à un pile à combustible, dans lequel deux plaques monopolaires (1, 2) sont fabriquées et assemblées. Selon l'invention, les plaques monopolaires (1, 2) sont directement ou indirectement soudées de manière inductive par l'intermédiaire d'au moins un corps (3), de préférence en forme de broche, disposé entre les plaques monopolaires (1, 2). L'invention concerne également une plaque bipolaire et un pile à combustible.
