Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung einer Membrananordnung mit einer Elektrolytmembran für eine Brennstoffzelle.The invention relates to a method for producing a membrane arrangement with an electrolyte membrane for a fuel cell.
Aus der
Der Erfindung liegt die Aufgabe zugrunde, ein gegenüber dem Stand der Technik verbessertes Verfahren zur Herstellung einer Membrananordnung mit einer Elektrolytmembran für eine Brennstoffzelle anzugeben.The invention has for its object to provide a comparison with the prior art improved method for producing a membrane assembly with an electrolyte membrane for a fuel cell.
Die Aufgabe wird erfindungsgemäß mit einem Verfahren gelöst, welches die im Anspruch 1 angegebenen Merkmale aufweist.The object is achieved by a method having the features specified in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
In dem Verfahren zur Herstellung einer Membrananordnung mit einer Elektrolytmembran für eine Brennstoffzelle wird erfindungsgemäß die Elektrolytmembran und/oder zumindest eine an der Elektrolytmembran angeordnete Katalysatorschicht an zumindest einem eine innere Ausschnittsfläche aufweisenden Rahmenelement derart befestigt, dass die Elektrolytmembran und/oder die zumindest eine Katalysatorschicht die innere Ausschnittsfläche vollständig überdecken und/oder in die Ausschnittsfläche hineinragen.In the method for producing a membrane arrangement having an electrolyte membrane for a fuel cell, according to the invention, the electrolyte membrane and / or at least one catalyst layer arranged on the electrolyte membrane are fastened to at least one frame element having an inner cutout surface in such a way that the electrolyte membrane and / or the at least one catalyst layer is the inner one Cover completely cut surface and / or protrude into the cut surface.
Mittels des Rahmenelements wird eine Abdichtung der Elektrolytmembran und/oder der Katalysatorschicht gegenüber einer Bipolarplatte, d. h. zwischen der Wasserstoffseite und der Sauerstoffseite innerhalb der Brennstoffzelle in einfacher Weise realisiert. In besonders vorteilhafter Weise wird die Elektrolytmembran oder die gesamte Membrananordnung im Randbereich mit dem Rahmenelement vergrößert. Das Rahmenelement ist dabei aus einem besonders kostengünstigen Material gebildet, so dass die Vergrößerung mit geringen Kosten realisierbar ist. Weiterhin resultiert aus der erfindungsgemäßen Ausbildung des Verfahrens die Möglichkeit einer besonders einfachen Herstellbarkeit der Membrananordnung und einer vereinfachten Handhabung der Elektrolytmembran während ihrer Herstellung, da nur wenige Bauteile und Werkstoffe verarbeitet werden. Auch können weitere Komponenten in einfacher Weise mit dem Rahmenelement verbunden, insbesondere verklebt werden. Die weiteren Komponenten umfassen beispielsweise ein oder mehrere Gasdiffusionslagen.By means of the frame member, a sealing of the electrolyte membrane and / or the catalyst layer with respect to a bipolar plate, d. H. realized between the hydrogen side and the oxygen side within the fuel cell in a simple manner. In a particularly advantageous manner, the electrolyte membrane or the entire membrane arrangement is enlarged in the edge region with the frame element. The frame element is formed from a particularly cost-effective material, so that the enlargement can be realized at low cost. Furthermore, from the inventive design of the method results in the possibility of a particularly simple manufacturability of the membrane assembly and a simplified handling of the electrolyte membrane during its production, since only a few components and materials are processed. Also, other components can be easily connected to the frame member, in particular glued. The other components include, for example, one or more gas diffusion layers.
