Abstract

The invention discloses a fuel cell thermal management system which comprises a cooling liquid circulation main path and a fuel cell connected in series in the cooling liquid circulation main path, and the fuel cell comprises a cell water inlet and a cell water outlet. A main circulating water pump and a first three-way reversing valve are sequentially arranged on the cooling liquid circulating main path in series in the direction from the battery water outlet to the battery water inlet, the first three-way reversing valve is further connected to the battery water inlet through a cold start bypass, and a heating device used for heating cooling liquid is arranged on the cold start bypass. According to the invention, the cold start bypass is arranged, and the heating device is used for heating the cooling liquid, so that the temperature of the fuel cell is rapidly increased, and the cold start time is shortened. The invention also discloses a fuel cell system comprising the fuel cell thermal management system.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell thermal management system and a fuel cell system. Background technique [0002] With the gradual industrialization of fuel cell systems for vehicles, the thermal management requirements for fuel cell vehicles will also be gradually improved. Fuel cell thermal management systems face the problem of cold start difficulties in low temperature environments. The traditional engine can be started directly at low temperature for 1-2 minutes to complete the heat engine, but the fuel cell system is difficult to start at low temperature, and it cannot be compared with the traditional fuel vehicle. Poor, unable to achieve rapid power output, resulting in failure to start or start-up takes a long time. [0003] Therefore, how to realize the rapid start-up of the fuel cell system at low temperature is a technical problem to be solved by those skilled in the art. Contents of ...
