PROBLEM TO BE SOLVED: To provide a fuel cell system capable of preventing combustion exhaust gas from flowing out to the outdoor through a drainage path in a water collection section without discharging quality water used in the fuel cell main unit even when a discharge path for discharging the combustion exhaust gas to the outside is clogged.SOLUTION: The fuel cell system includes: a first water collection section 85 for recovering moisture contained in the exhaust gas flowing in a first exhaust path 77 within a fuel cell system 100 as condensed water; and a second water collection section 91 for collecting rain water flowing in a second exhaust path 70 outside the fuel cell system 100 connected to the first exhaust path. The first water collection section 85 and the second water collection section 91 are connected via a first drainage path 87 so that the second water collection section 91 has a water-sealing function. This prevents exhaust gas from leaking from the fuel cell system into a house through the drainage path as well as the quality condensed water used for power generation by the fuel cell main unit is prevented from being discharged. |
