To ensure an output performance (EP) of a fuel cell stack (3) without providing excessive operation restriction, a controller (43) of a fuel cell system (1) is provided with: an operation restrictor (45) configured to restrict an operation of the stack (3) so that a delivered air temperature (T 2 ) of an air compressor (7) is kept from exceeding its upper limit (Lt) based on a sucked air temperature (T 1 ) detected by a temperature sensor (27) and an atmospheric pressure (P 0 ) detected by a pressure sensor (25), and configured to mitigate the restriction of the operation under a condition that drop of the sucked air temperature (T 1 ) is predicted; and an upper limit setter (47) configured to set an upper limit (Lp) of a delivered air pressure (P 2 ) of the air compressor (7) so that a temperature (T 2 ) of air delivered by the air compressor (7) is kept from exceeding its upper limit (Lt), based on the sucked air temperature (T 1 ) detected by the temperature sensor (27) and the atmospheric pressure (P 0 ) detected by the pressure sensor (25). |
