PROBLEM TO BE SOLVED: To provide a fuel cell system in which discharge processing during fluid discharge processing is performed more sufficiently and thereby water is not left in the system, and a fluid discharge method in the system.SOLUTION: A control unit discharges water in a hydrogen discharge passage 33 by: controlling a flow volume of a fluid in an anode passage 2B at an anode outlet 2c of a fuel cell 2 to a first flow volume; then controlling a flow volume in the anode passage 2B at the anode outlet 2c to a second flow volume less than the first flow volume; and opening an exhaust drain valve 31 when the second flow volume flows. After flowing at the first flow volume, the flow volume of a fluid in the anode passage 2B at the anode outlet 2C may be flown at a third flow volume less than the first flow volume and more than the second flow volume.SELECTED DRAWING: Figure 2 |
