Erfindungsgemäß ist die Absperrvorrichtung (3) zumindest teilweise in die Befeuchtungseinheit (2) und/oder in den Wärmetauscher integriert angeordnet.The invention relates to a fuel cell device (1), comprising - at least one fuel cell, which is connected to a humidification unit (2) and / or a heat exchanger via at least one flow channel, and - a shut-off device (3) for closing the at least one flow channel, if the Fuel cell device (1) is out of operation. According to the invention, the shut-off device (3) is at least partially integrated in the moistening unit (2) and / or in the heat exchanger.
Description
Die Erfindung betrifft eine Brennstoffzellenvorrichtung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a fuel cell device according to the preamble of claim 1.

Der Erfindung liegt die Aufgabe zu Grunde, eine gegenüber dem Stand der Technik verbesserte Brennstoffzellenvorrichtung anzugeben.The invention is based on the object to provide a comparison with the prior art improved fuel cell device.
Die Aufgabe wird erfindungsgemäß mit den in Anspruch 1 angegebenen Merkmalen gelöst.The object is achieved with the features specified in claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Eine Brennstoffzellenvorrichtung umfasst mindestens eine Brennstoffzelle, die mit einer Befeuchtungseinheit und einem Wärmetauscher über wenigstens einen Strömungskanal verbunden ist, und eine Absperrvorrichtung zum Verschließen des wenigstens einen Strömungskanals, wenn das Brennstoffzellensystem außer Betrieb ist. Erfindungsgemäß ist die Absperrvorrichtung zumindest teilweise in die Befeuchtungseinheit und/oder in den Wärmetauscher integriert angeordnet.A fuel cell device comprises at least one fuel cell connected to a humidification unit and a heat exchanger via at least one flow channel, and a shut-off device for closing the at least one flow channel when the fuel cell system is out of operation. According to the invention, the shut-off device is at least partially integrated in the moistening unit and / or in the heat exchanger.
Bei der derart ausgebildeten Brennstoffzellenvorrichtung wird zur Anordnung der Absperrvorrichtung ein bereits vorhandener Bauraum genutzt, so dass gegenüber dem Stand der Technik, in dem die Absperrvorrichtung üblicherweise als separate Komponente in einem Strömungskreislauf eingebunden ist, Kosten und Bauraum eingespart werden. Hierbei sind separate Schnittstellen, erforderliche Dichtungselemente und Verbindungselemente im Bereich des Strömungskanals sowie die dazu erforderlichen Montageschritte gegenüber dem Stand der Technik verringert. Die Absperrvorrichtung ist dabei dazu vorgesehen, den Strömungskanal zu verschließen, wenn das Brennstoffzellensystem außer Betrieb ist, so dass die Zufuhr von Reaktanten zur Brennstoffzelle, insbesondere die Zufuhr von Luft zu einer Kathode der Brennstoffzelle, außerhalb des Betriebs vermieden wird.In the case of the fuel cell device designed in this way, an already existing installation space is used for the arrangement of the shut-off device, so that costs and installation space are saved compared to the prior art, in which the shut-off device is usually incorporated as a separate component in a flow circuit. In this case, separate interfaces, required sealing elements and connecting elements in the region of the flow channel as well as the necessary assembly steps compared to the prior art are reduced. The shut-off device is intended to close the flow channel when the fuel cell system is out of operation, so that the supply of reactants to the fuel cell, in particular the supply of air to a cathode of the fuel cell, is avoided outside of the operation.
Ausführungsbeispiele der Erfindung werden im Folgenden anhand einer Zeichnung näher erläutert.Embodiments of the invention will be explained in more detail below with reference to a drawing.

Die einzige
Die Brennstoffzellenvorrichtung
Dies ist insbesondere wenigstens eine Brennstoffzelle, welche eine Anzahl von Einzelzellen aufweist, die zu einem Brennstoffzellenstapel zusammengefasst sind. Die Einzelzellen umfassen jeweils eine Kathode und eine Anode, zwischen denen eine protonenleitende Membran angeordnet ist. Die Brennstoffzelle umfasst somit einen Anodenraum und einen Kathodenraum, wobei dem Kathodenraum ein Oxidationsmittel, insbesondere Luft, und dem Anodenraum ein Brennstoff, insbesondere Wasserstoff, über Medienleitungen zugeführt wird, die jeweils einen Strömungskanal bilden.This is in particular at least one fuel cell, which has a number of individual cells, which are combined to form a fuel cell stack. The individual cells each comprise a cathode and an anode, between which a proton-conducting membrane is arranged. The fuel cell thus comprises an anode space and a cathode space, wherein the cathode space an oxidant, in particular air, and the anode space, a fuel, in particular hydrogen, is supplied via media lines, each forming a flow channel.
Für eine zuverlässige Funktionsfähigkeit der Brennstoffzelle, welche aus den ihr zugeführten Edukten elektrische Leistung generiert, ist eine entsprechende Befeuchtung der zuströmenden Medien erforderlich. Die Befeuchtung erfolgt mittels der Befeuchtungseinheit
