A fuel cell system includes: a fuel cell module having a plurality of sets of a film/electrode assembly and a flow channel forming member which forms a flow channel for a reaction gas supplied to the film/electrode assembly; and a treatment execution unit which executes a treatment for increasing the amount of water held in each of flow channel forming members so as to reduce irregularities of water amount held in the flow channel forming members. This can reduce irregularities of the water amount held in the flow channel forming members.
