Abstract

The invention relates to the technical field of fuel cells, and particularly discloses a fuel cell thermal management system, which comprises a controller, a fuel cell, a circulating device, a heat exchange device, a medium compensation and storage device and a pressure adjusting device, the controller can compare pressure signals of the first pressure detection device and the second pressure detection device with a preset pressure target value to generate a pressure control signal; the pressure adjusting device can adjust the flow resistance of the circulating medium according to the pressure control signal. The invention also discloses a pressure regulation method of the fuel cell thermal management system. The fuel cell thermal management system provided by the invention can realize effective control of pressure.

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 pressure regulation method for the fuel cell thermal management system. Background technique [0002] In order to keep the fuel cell working safely and efficiently, its temperature needs to be controlled within an appropriate range. The thermal management system of the fuel cell is based on the circulating medium, through the flow of the circulating medium between the fuel cell and the heat exchange device to provide the heat required by the fuel cell, or take away the excess heat of the fuel cell, so that the fuel cell can work at target temperature level. The circulating medium is generally driven by the circulating device. According to the difference of the heat exchange, the circulating device needs to drive the circulating medium to flow at different flow rates. While achieving the target heat exchange, ensure that the temperat...
