Description
Die Erfindung betrifft eine Tankvorrichtung zur Speicherung von verdichteten Fluiden mit einer Sensorvorrichtung, insbesondere für einen Brennstoffzellentank zur Speicherung von Wasserstoff, beispielsweise zur Anwendung in Fahrzeugen mit Brennstoffzellenantrieb. Ferner betrifft die Erfindung ein Verfahren zur Herstellung der Sensorvorrichtung und eine Brennstoffzellenanordnung mit solch einer Tankvorrichtung.The invention relates to a tank device for storing compressed fluids with a sensor device, in particular for a fuel cell tank for storing hydrogen, for example for use in vehicles with fuel cell drives.

Stand der TechnikState of the art
Die
Für die Überwachung der Druckverhältnisse in der Tankvorrichtung werden typischerweise Drucksensorvorrichtungen eingesetzt, die aufgrund ihres Einsatzbereichs mit Wasserstoff in Kontakt treten. Daher werden die Drucksensorvorrichtungen aus Werkstoffen hergestellt, die in der Regel keine oder nur wenig Anfälligkeit zur Wasserstoff-Versprödung aufweisen.To monitor the pressure conditions in the tank device, pressure sensor devices are typically used which, due to their area of application, come into contact with hydrogen. The pressure sensor devices are therefore made from materials which generally have little or no susceptibility to hydrogen embrittlement.
Heutzutage werden die Sensorvorrichtungen typischerweise aus einem geeigneten Stahl gefertigt, beispielsweise aus der Klasse der Martensite. Martensite sind kostengünstig und weisen eine hohe mechanische Festigkeit auf.Nowadays the sensor devices are typically made of a suitable steel, for example of the martensite class. Martensites are inexpensive and have high mechanical strength.
Dennoch kann auch hier eine Wasserstoff-Versprödung auftreten, was zu einer Beschädigung der Sensorvorrichtung führen kann. Dadurch ist keine präzise Druckangabe mehr möglich, was zu einer Beeinträchtigung der Funktionsweise der Tankvorrichtung führt.Nevertheless, hydrogen embrittlement can also occur here, which can lead to damage to the sensor device. As a result, precise pressure information is no longer possible, which leads to an impairment of the functioning of the tank device.
