Abstract

An FC (fuel cell) system includes: a compressor supplying air to a CE (cathode electrode) of FC; an OV (outlet valve) connected to a discharge port through which air is discharged from CE; an injector supplying hydrogen gas to an AE (anode electrode) of FC; a CP (circulation pump) provided in a circulation path that returns the hydrogen gas discharged from AE to AE; and a controller controlling power generation of FC. In a case of removing a component that allows air to enter CE when removed, before the component is removed, the controller executes a first step of opening OV, driving the compressor, and supplying air to CE, and a second step of driving CP to cause hydrogen gas that remains inside AE and the circulation path to be circulated in a state in which the hydrogen gas is not supplied to AE from the injector.
