| 摘要 |
The present invention relates to a fuel cell system which inhibits a dry state of an electrolyte membrane of a fuel cell from being prolonged. The fuel cell system comprises: the fuel cell (100) having the electrolyte membrane (90); a sensor (450) which measures the temperature of the fuel cell (100); and a control unit (610). The control unit allows the fuel cell (100) to perform a wet operation, that water balance on a cathode side with respect to the fuel cell (100) is higher than the water balance on the cathode side during normal operation of the fuel cell (100), when the temperature of the fuel cell (100), measured by the sensor (450), is maintained to be equal to or higher than a first threshold temperature for a predetermined time, and then the temperature of the fuel cell (100), measured by the sensor (450), becomes lower than a second threshold temperature, which is the temperature lower than or equal to the first threshold temperature. |
