Abstract
An object of the present invention is to provide a fuel cell system and a method of operating the fuel cell system which is difficult to give an uncomfortable feeling to a driver or passenger by operation sound of the injector while satisfactorily discharging water. The fuel cell system includes a fuel cell stack having an anode flow path, an injector for supplying hydrogen at a predetermined drive cycle toward the anode flow path by being opened, and an ECU for controlling the injector, wherein the ECU performs a valve opening time extension step in which hydrogen is supplied in a valve opening time longer than that in next and previous drive cycles.
