Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fuel cell system capable of easily determining whether or not a pressure detection element provided in a fuel gas passage has a malfunction.SOLUTION: A control section 100 drives a gas pump 60 in a state where a shutoff valve 69 is closed or opens the shutoff valve 69 from the closed state (i), and determines whether or not at least one of a pressure switch 61 and a gas source 63 is abnormal on the basis of the pressure variation detected by the pressure switch 61 (ii).
