Abstract
Es wird ein Brennstoffzellensystem mit wenigstens einem Brennstoffzellenstack (10) vorgeschlagen, der eine Anodenseite (12) aufweist, der über ein Anodensystem Brennstoff zugeführt wird und der eine Kathodenseite (14) aufweist, der über ein Kathodensystem Luft zugeführt wird. Das Kathodensystem weist wenigstens einen Luftverdichter (20) auf, durch den verdichtete Luft zur Kathodenseite (14) gefördert wird, wobei der wenigstens eine Luftverdichter (20) einen elektrischen Antriebsmotor (34) aufweist, der durch eine elektronische Steuereinrichtung (40) bedarfsabhängig angesteuert wird. Ein Betriebszustand des wenigstens einen Luftverdichters (20) wird durch eine mit der Steuereinrichtung (40) verbundene Sensoreinrichtung (42) erfasst. Die Sensoreinrichtung (42) umfasst wenigstens einen außerhalb des wenigstens einen Luftverdichters (20) angeordneten Ultraschallsensor (44), durch den der im Ultraschallbereich emitierte Schall des wenigstens einen Luftverdichters (20) erfasst wird.A fuel cell system is proposed with at least one fuel cell stack (10) which has an anode side (12) which is supplied with fuel via an anode system and which has a cathode side (14) which is supplied with air via a cathode system. The cathode system has at least one air compressor (20) through which compressed air is conveyed to the cathode side (14), the at least one air compressor (20) having an electric drive motor (34) which is controlled by an electronic control device (40) as required . An operating state of the at least one air compressor (20) is detected by a sensor device (42) connected to the control device (40). The sensor device (42) comprises at least one ultrasonic sensor (44) which is arranged outside the at least one air compressor (20) and by which the sound emitted in the ultrasonic range of the at least one air compressor (20) is detected.
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einem Brennstoffzellensystem nach der Gattung des Anspruchs 1.The invention is based on a fuel cell system according to the preamble of claim 1.
Eine solches Brennstoffzellensystem ist durch die
Vorteile der ErfindungAdvantages of the invention
Das erfindungsgemäße Brennstoffzellensystem mit den Merkmalen gemäß Anspruch 1 hat demgegenüber den Vorteil, dass durch den Ultraschallsensor außerhalb des Luftverdichters eine Erfassung von dessen Betriebszustand ermöglicht ist, so dass der Luftverdichter einfach ausgebildet sein kann und entsprechend kostengünstig ist.The fuel cell system according to the invention with the features according to claim 1 has the advantage that the ultrasonic sensor outside the air compressor enables its operating state to be detected, so that the air compressor can be designed simply and is correspondingly inexpensive.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Brennstoffzellensystems angegeben. Die Ausbildung gemäß Anspruch 2 hat den Vorteil, dass kein zusätzlicher Ultraschallsensor erforderlich ist indem ein in den meisten Kraftfahrzeugen bereits vorhandener Ultraschallsensor eines Parkhilfesystems zur Ermittlung des Betriebszustands des Luftverdichters verwendet wird. Die Ausbildung gemäß einem der Ansprüche 4 bis 6 hat den Vorteil, dass der vom Luftverdichter abgestrahlte Ultraschall verstärkt wird und dadurch eine verbesserte Erfassung durch den Ultraschall ermöglicht ist. Die Ausbildung gemäß Anspruch 7 ermöglicht die Ermittlung möglicher Schädigungen des Luftverdichters, was gemäß Anspruch 8 bei der Ansteuerung des Antriebsmotors des Luftverdichters berücksichtigt werden kann oder gemäß Anspruch 9 in einer Diagnose- oder Warneinrichtung berücksichtigt werden kann. Hierbei kann beispielsweise ein Servicehinweis oder eine Abschaltung des Brennstoffzellensystems bewirkt werden wenn eine zu starke Schädigung des Luftverdichters vorhanden ist.Advantageous configurations and developments of the fuel cell system according to the invention are specified in the dependent claims. The embodiment according to claim 2 has the advantage that no additional ultrasonic sensor is required in that an ultrasonic sensor of a parking aid system that is already present in most motor vehicles is used to determine the operating state of the air compressor. The embodiment according to one of claims 4 to 6 has the advantage that the ultrasound emitted by the air compressor is amplified and thereby improved detection by the ultrasound is made possible. The design according to claim 7 enables the determination of possible damage to the air compressor, which according to claim 8 can be taken into account when controlling the drive motor of the air compressor or according to claim 9 can be taken into account in a diagnostic or warning device. In this case, for example, a service note or the fuel cell system can be switched off if the air compressor is damaged too much.
