Abstract

An expansion tank provided by the present application reduces the volume occupied by a fuel cell system and improves the integration level by arranging a deionizer in the tank body. At the same time,since the deionizer is integrated in the expansion tank, when replacing the deionizer, it is not necessary to completely drain the coolant in the system, thereby saving the replacing time. Further, the tank body is provided with an overflow pipe opening, which can ensure that the coolant pressure is controllable and can be balanced with the pressure of air and hydrogen on both sides; The expansiontank can effectively solve the problem that the coolant overflows into the expansion tank when the water pump stops suddenly, ensure that the coolant of the fuel cell is not polluted, and ensure thesafety of the fuel cell operation and the like.

Description

technical field [0001] The present application relates to the technical field of fuel cells, in particular to an expansion tank and a fuel cell thermal management system. Background technique [0002] Due to the particularity of the fuel cell, the conductivity of the coolant in the fuel cell system is required to be less than 5 μs / cm. In the thermal management system of the fuel cell system, the commonly used tube-and-belt radiators, PTCs, air compressors and other components will lead to an increase in the conductivity of the coolant. In addition, due to the small size of the deionized resin particles, the flow resistance is relatively large. How to effectively reduce the conductivity of the coolant in the thermal management system and how to reduce the influence of the flow resistance of the deionizer on the flow of the system are difficult problems to be solved by the fuel cell thermal management system. [0003] In the prior art, the deionizer is installed outside the ...
