Titel
(DE) Brennstoffzellensystem mit Sensor zur Erfassung von Druckschwankungen in einem Fluidversorgungsstrang
(EN) Fuel cell system, has sensor to detect impact sound and pressure fluctuations in fluid supply strand, and attached to fluid supplying and/or fluid control elements, fluid compressor and control valve
Zusammenfassung
(DE)

Die vorliegende Erfindung betrifft ein Brennstoffzellensystem (1) mit einem Fluidversorgungs- und/oder Fluidkontrollelement. Sie zeichnet sich dadurch aus, dass ein Sensor (31) zur Erfassung Druckschwankungen und/oder Druckspitzen in einem Fluidversorgungsstrang (3, 4) vorgesehen ist.

(EN)

The system (1) has fluid supply and fluid control elements e.g. anode remaining-gas compressor (29) and electrical connector (27). A sensor (31) i.e. sound sensor, detects pressure fluctuations in a fluid supply strand (3). The sensor is attached to the fluid supplying and/or fluid control elements, a fluid compressor (10) i.e. turbine compressor, and a control valve (32). The sensor is provided for detection of impact sound. A pressure sensor (21) and an air quantity measuring device (37) are provided.
