PROBLEM TO BE SOLVED: To provide a fuel cell system capable of recovering water supplied to a fuel cell without lowering efficiency. SOLUTION: The fuel cell system furnished with a device to pressure supply air to the fuel cell 101 through an air compressor 103, a device to supply water reserved in a water tank 110 to pressurized air, a condenser 112 to recover moisture in exhaust gas of the fuel cell in the water tank by condensing it and a device to cool the condenser is devised to decide each of target values to put water variation in the water tank within a standard range and to minimize a sum of energy consumption of the air supply device and the cooling device in accordance with demand output of the fuel cell. |
