[0052] The present invention will be further described below in conjunction with the drawings and the following embodiments. It should be understood that the drawings and the following embodiments are only used to illustrate the present invention, not to limit the present invention.
[0053] Aiming at the shortcomings of the existing cooling system of the fuel cell system for vehicles. The present invention provides a cooling system for a vehicle fuel cell system, which is used for heat dissipation of the fuel cell system. Such as figure 1 As shown, the cooling system includes: a circulating pump 8; a temperature control valve 2 with five openings corresponding to five flow channels; and a temperature control valve 2 connected (for example, connected by a wiring harness) to control each of the temperature control valve 2 The opening degree of the fuel cell control unit (FCU) 1. Among them, the first flow passage 12 sequentially connects the circulation pump 8, the fuel cell sta...
