A fuel cell system includes an information processor and a fuel cell unit connected to the information processor. The fuel cell unit has a cell stack which includes a plurality of single cells stacked in layers on one another, a fuel passage, and an air passage, and generates electric power based on a chemical reaction, a fuel supply section which supplies a fuel to the anode through the fuel passage, and an air supply section which supplies air to the cathode through the air passage. The information processor has a power controller which manages an operation of the fuel cell unit. The power controller stops power generation in the cell stack and executes maintenance processing such that air from the air supply section is caused to flow through the air passage of the cell stack, when generated power output of the cell stack is lower than a predetermined output.
