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

摘要

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.
