To provide a fuel cell system configured to suppress the occurrence of partial fuel gas deficiency in a fuel cell. A fuel cell system wherein at least one injector selected from the group consisting of a first injector and a second injector is driven by duty ratio control to maintain a fuel gas pressure to the fuel cell within a predetermined range, in accordance with an output current value; wherein a controller determines whether or not the output current value is larger than a predetermined first threshold; and wherein, when the controller determines that the output current value is larger than the predetermined first threshold, the controller drives the first injector by duty ratio control, and the controller drives the second injector by duty ratio control to open a valve of the second injector at least while a valve of the first injector is closed.
