PROBLEM TO BE SOLVED: To provide a technology capable of suppressing excessive drainage from a fuel cell.SOLUTION: A fuel cell system 100 comprises a drainage switch 11, control unit 15, fuel cell 20, and cathode gas supply unit 30. The control unit 15 has a function as a drainage processing execution unit 16 and a function as a water content detection unit 18. The drainage processing execution unit 16, when having accepted a drainage instruction from a driver through the drainage switch 11, executes air-scavenging processing of the cathode gas supply unit 30 supplying ambient air, as an air-scavenging gas, to the fuel cell 20 to discharge water from the inside of the fuel cell 20. The drainage processing execution unit 16 nullifies the drainage instruction from the driver or reduces a drainage amount from the fuel cell 20 by changing an execution condition of the air-scavenging processing, when a water content inside the fuel cell 20 acquired by the water content detection unit 18 is equal to or lower than a predetermined threshold.SELECTED DRAWING: Figure 1 |
