  "textContent": "A fuel cell system includes a fuel cell stack, a fuel gas supply path, an injector, an ejector, a circulation path, an outlet port pressure detection unit, and a control device. The control device stops driving the injector when an ejector outlet port pressure is equal to or more than a required upper limit value with the injector driven, and drives the injector when the ejector outlet port pressure is equal to or less than a required lower limit value with the injector stopped. The control device reduces the required upper limit value stepwise and reduces the required lower limit value stepwise in a range defined by a first target upper limit value and a second target upper limit value when a required load is varied from a first required load to a second required load and a load reduction amount is more than a first predetermined load.",
