| Zusammenfassung: | A fuel cell system capable of easily determining the presence or absence of abnormality of a pressure sensing element (61) provided in a fuel gas passage (6) is to be provided. A control unit 100 (i) drives a gas pump 60 in a state in which a cutout valve 69 is closed or opens the cutout valve 69 from the closed state, and (ii) determines whether or not at least one of a pressure switch 61 and a gas source 63 is abnormal on the basis of variations in pressure sensed by the pressure switch 61. |
