Abstract

The invention discloses a temperature control system, method and equipment of a fuel cell stack. The temperature control system of the fuel cell stack comprises: the fuel cell stack and a draught fan,wherein the draught fan is used for providing air volume for an air duct; a variable heat dissipation air duct which is arranged between the fuel cell stack and the fan and at least comprises a plurality of heat dissipation sub-air ducts; and a controller which is used for adjusting the opening number or the closing number of the heat dissipation sub-air ducts so as to control the temperature ofthe fuel cell stack. According to the invention, the technical problem of non-uniform temperature distribution of the fuel cell stack in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of fuel temperature control, in particular to a fuel cell stack temperature control system, control method, and control equipment. Background technique [0002] In related technologies, the proton exchange membrane fuel cell is a new fuel energy source with high efficiency, low noise, and less pollution. The efficiency of a conventional proton exchange membrane fuel cell stack reaches about 50%, and half of the energy will be released in the form of heat. If the heat of the fuel cell cannot be discharged in time, the temperature of the battery stack will rise sharply, which will cause the dehydration of the membrane and cause the performance of the battery stack to decline, and in severe cases will cause irreversible damage to the battery, that is, there is a serious heating problem in the fuel cell stack during operation. The current heat dissipation method of the battery stack is to sandwich the he...
