PROBLEM TO BE SOLVED: To suppress occurrence of an abnormal noise or the like as the operation sound of a circulation device.SOLUTION: A fuel battery system includes: a fuel battery; an anode gas supply flow channel for supplying anode gas to the fuel battery; an anode gas discharge flow channel for discharging anode off-gas from the fuel battery; an anode gas circulation flow channel for connecting the anode gas supply flow channel to the anode gas discharge flow channel; a circulation device disposed on the anode gas circulation flow channel for supplying the anode off-gas to the anode gas supply flow channel; and a control part for, when moisture remains in the circulation device, controlling the circulation flow rate of the circulation device to discharge moisture. The control part is configured to, when it is determined that moisture content remaining in the circulation device is equal to or more than a predetermined value, limit the rise rate of the circulation flow rate of the circulation device.SELECTED DRAWING: Figure 1 |
