To provide a cooling system for a fuel cell mounting vehicle capable of suitably carrying out cooling according to a driving state of a vehicle.
In the vehicular cooling system 10, an air conditioner radiator 42 on an upstream side of vehicle speed wind, and a fuel cell radiator 62 on a downstream side are disposed so as to be superimposed with each other in a flow passage of the vehicle speed wind. A controlling computer 80 of the cooling system 10 judges whether the temperature of a fuel cell stack 32 is not less than a predetermined value or not. As a result of that, if not less than the predetermined value TH, as a radiator mounting variable control, an installation position of a heat exchanger unit 42a constituting the air conditioner radiator 42 or installation positions of the heat exchanger unit 42a and a heat exchanger unit 42b are moved toward an upper surface direction, thereby increasing the vehicle speed wind led to the fuel cell radiator 62 without raising temperature by the air conditioner radiator 42 and lowering wind speed.
