  "textContent": "The fuel cell system includes: a fuel cell; an anode supply pipe; a fuel gas supplier disposed at the anode supply pipe, the fuel gas supplier configured to adjust a supply quantity of a fuel gas to be supplied to the fuel cell; an ejector disposed at the anode supply pipe at a position between the fuel gas supplier and the anode supply port; an anode circulation pipe connected to the anode discharge port and the ejector; a circulation stop unit disposed at the anode circulation pipe, the circulation stop unit configured to stop circulation of the fuel gas through the anode circulation pipe; a pressure sensor configured to detect a pressure in the anode supply pipe at a position between the ejector and the anode supply port; and a controller. When a first pressure acquired from the pressure sensor is equal to or less than a predetermined lower limit value, the controller controls the fuel gas supplier to perform constant quantity supply control to supply the fuel gas of a predetermined supply quantity, and controls the circulation stop unit to perform circulation stop control to stop the circulation through the anode circulation pipe, and the controller determines abnormality at the ejector and the anode circulation pipe by using a second pressure acquired from the pressure sensor after the fuel gas supplier performs the constant quantity supply control and the circulation stop unit performs the circulation stop control.",
