ABSTRACT:
A fuel cell system (10) of the present invention has a fuel cell (20) which generates electric power by being supplied with reactive gas, an air compressor (C1) which supplies oxidizing gas to the fuel cell (20), a pressure sensor (P2) which detects the pressure of oxidizing gas, a pressure control valve (C2) which adjusts the pressure of oxidizing gas, and a control device (50) which adjusts the valve opening of the pressure control valve (C2) on the basis of the pressure detected by the pressure sensor (P2). When an abnormality in the pressure sensor (P2) is detected, the control device (50) opens the pressure control valve (C2) so that the valve opening thereof is equal to or larger than a predetermined opening. This arrangement ensures that the cell operation can be continued for a while instead of being immediately stopped in the event of abnormality in the pressure sensor (P2).
