Die
Der Erfindung liegt die Aufgabe zugrunde, ein gegenüber dem Stand der Technik verbessertes Verfahren sowie eine verbesserte Vorrichtung zur Herstellung von Bauelementen für eine elektrochemische Zelle, insbesondere eine Brennstoffzelle, oder einen elektrochemischen Energiespeicher anzugeben, wodurch insbesondere eine optimierte Geometrie der hergestellten Bauelemente ermöglicht ist.The invention has for its object to provide a comparison with the prior art improved method and an improved apparatus for producing components for an electrochemical cell, in particular a fuel cell, or an electrochemical energy storage, which in particular an optimized geometry of the manufactured components is possible.
Hinsichtlich des Verfahrens wird die Aufgabe erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale gelöst. Hinsichtlich der Vorrichtung wird die Aufgabe erfindungsgemäß durch die im Anspruch 2 angegebenen Merkmale gelöst.With regard to the method, the object is achieved by the features specified in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Beim Verfahren zur Herstellung von Bauelementen für eine elektrochemische Zelle, insbesondere eine Brennstoffzelle, oder einen elektrochemischen Energiespeicher wird in einem mehrstufigen Prozess ein flächiges Bauelement erfindungsgemäß in einem ersten Umformschritt hydromechanisch umgeformt und in einem zweiten Umformschritt mechanisch nachgeformt. Dadurch ist eine optimierte Ausformung der Geometrie des Bauelements ermöglicht.In a method for producing components for an electrochemical cell, in particular a fuel cell, or an electrochemical energy store, in a multistage process a planar component is hydromechanically deformed in a first forming step and mechanically formed in a second forming step. This allows optimized shaping of the geometry of the component.
Besonders vorteilhafterweise können enge und tiefe Kanäle sowie ebene Kanalbereiche im Bauelement realisiert werden, woraus eine verbesserte Funktionalität des Bauelements resultiert.Particularly advantageously, narrow and deep channels and even channel regions can be realized in the component, resulting in improved functionality of the component.
Bei der Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens ist das flächige Bauelement mit einer mehrstufigen Umformvorrichtung hydromechanisch umformbar und anschließend mechanisch nachformbar. Eine solche mehrstufige Umformvorrichtung ermöglicht die Reduzierung der Herstellungskosten des Bauelements.In the apparatus for carrying out the method according to the invention, the planar component with a multi-stage forming device is hydromechanically deformable and then mechanically nachformbar. Such a multi-stage forming device enables the reduction of the manufacturing cost of the device.
In einer besonders vorteilhaften Ausführungsform der Erfindung können die Bauteile bei der Nachformung für einen späteren Fügevorgang optimiert werden.In a particularly advantageous embodiment of the invention, the components can be optimized during the post-forming for a subsequent joining operation.
