PROBLEM TO BE SOLVED: To provide a fuel cell system, used under a low-temperature environment, capable of removing water inside a fuel cell in a short time, when operation is stopped. SOLUTION: This fuel cell system is provided with an output current control means 13 for controlling an output current of the fuel cell 10 and water amount detection means 24, 34 for detecting an amount of water remaining in the fuel cell 10 to set a target current value, based on the amount of water remaining in the fuel cell 10 detected by the water amount detection means 24, 34 and control, so that an output current of the fuel cell 10 becomes the target current value by the output current control means 13, when the normal operation of the fuel cell 10 ends. The target current value is set, in such away that it is reduced according to the reduction of the amount of water remaining in the fuel cell 10, the output current of the fuel cell 10 is increased, when water removal control is started to improve water evaporation rate, and the output current is reduced according to the reduction of the remaining water amount. |
