PROBLEM TO BE SOLVED: To provide fuel cell system capable of preventing exhaust gas from flowing to the outdoor from a drain port of a water recovery part even when an exhaust gas flow path for exhausting the exhaust gas to the outside is clogged.SOLUTION: A water recovery part 105 for recovering condensed water within an exhaust gas discharge path 28 is provided with a partition wall 122 to divide the water recovery part 105 into a first water pool part 120 which is connected to an exhaust gas discharge path 28 and a second water pool part 121 connected to a drain port. By controlling the gas supplied from a gas supply unit so that the pressure within the exhaust gas discharge path 28 is smaller than a pressure difference corresponding to the water level in a water-sealed structure, the exhaust gas is prevented from flowing to the outdoor from a drain path of the water recovery part. |
