FUEL CELL SYSTEM

A fuel cell system including a temperature detection part configured to detect temperatures of respective fuel cells, a cooling system including a cooling medium supply part configured to supply a cooling medium to each of the plurality of fuel cells, a power storage device, and a microprocessor. When a temperature of a first fuel cell detected by the temperature detection part becomes equal to or higher than a predetermined temperature, the microprocessor is configured to control the cooling system so as to cool the first and second fuel cells with a cooling capacity corresponding to a temperature of a second fuel cell having a lower temperature than the first fuel cell, performs an output limitation for the first fuel cell, and discharges an electric power from the power storage device in accordance with the output limitation.
