노이즈 바이브레이션의 억제와 소비 전력의 저감을 양립한다. 제어부는, 연료 전지 탑재 차량의 속도에 기초하여, 라디에이터 팬의 구동 전압의 상한을 설정하고, 연료 전지의 발전 전력으로부터 연료 전지의 발열량을 산출하고, 상기 라디에이터 팬의 구동 전압의 상한 하에서, 발열량을 방열할 수 있으며, 또한 냉각액 펌프와 라디에이터 팬에서 소비되는 전력이 최소로 되도록, 냉각액 펌프의 유량과 라디에이터 팬의 구동 전압과, 라디에이터에 흐르는 냉각액과 라디에이터를 바이패스하는 바이패스관에 흘리는 냉각액의 분류비를 조정하는 냉각 제어를 실행한다.
A fuel cell system comprises: a fuel cell; a cooling system circuit including a cooling liquid supply path configured to supply a cooling liquid to the fuel cell, a radiator configured to cool down the cooling liquid, a radiator fan, and a cooling liquid pump provided in the cooling liquid supply path to feed the cooling liquid to the fuel cell; a controller; and a speedometer configured to obtain a speed of the fuel cell vehicle, wherein the controller is capable of performing a first cooling control that sets an upper limit value of driving amount of the radiator fan according to the speed of the fuel cell vehicle and regulates a flow rate of the cooling liquid pump or the driving amount of the radiator fan under the upper limit value of the driving amount of the radiator, so as to cool down the fuel cell.
