PROBLEM TO BE SOLVED: To provide a fuel cell system capable of controlling operations of a plurality of injectors by means of a small-sized power-saving control device.SOLUTION: A fuel cell system comprises: a flow channel 431 and a flow channel 432 for supplying a fuel gas to a fuel cell stack 20 and arranged in parallel to each other; an injector INJ1 and an injector INJ2 switching between an opened state and a closed state of the flow channel 431 and the flow channel 432, respectively; and a first controller CTR1 and a second controller CTR2 controlling magnitude of currents supplied to the injector INJ1 and the injector INJ2 to predetermined values to maintain the flow channel 431 and the flow channel 432 to the opened state respectively. The first controller CTR1 controls the current supplied to the injector INJ1 to the predetermined value by chopper control of the switching element. The second controller CTR2 controls the current supplied to the injector INJ2 to the predetermined value by a resistor SR connected in series to a power supply. |
