An object of the present invention is to maintain a desired water treatment function with a simple and compact configuration, improve durability, and extend a maintenance cycle. A fuel cell system includes a fuel cell module, a water supply device that supplies water to the fuel cell module, a water container that supplies water to the water supply device, and the fuel cell. A condenser 18 that condenses water vapor in the exhaust gas discharged from the module 12 and supplies the condensed water to the water container 16 is provided. The water container 16 meanders the supply port 22 to which water is supplied from the condenser 18, the discharge port 24 for sending the water to the water supply device 14, and the meander for circulating the water from the supply port 22 to the discharge port 24. A water passage 26 is provided, and an ion exchange section 28 is disposed in the water passage 26. [Selection] Figure 1 |
