Fuel cell stack manifold assembly

Abstract

The invention relates to the technical field of automobiles, and particularly discloses a fuel cell stack manifold assembly, which comprises: a manifold main body, wherein the first end and the secondend of the manifold main body are respectively provided with a plurality of medium interfaces communicated with a stack; a two-stage steam-water separator which is used for separating water and hydrogen in the steam-water discharged from the electric pile, and comprises a low-speed steam-water separator and a high-speed steam-water separator which are communicated with each other; a water collecting mechanism which is used for collecting water discharged from the two-stage steam-water separator, and the water collecting mechanism is communicated with the two-stage steam-water separator, and the drain pipe communicates with the water collecting mechanism through an electromagnetic valve; and a heating mechanism that is arranged on one side of the water collecting mechanism and used for heating the electromagnetic valve and the cooling liquid outlet. According to the fuel cell stack manifold assembly provided by the invention, the integration level of a fuel cell stack system can be improved, and the fuel cell stack system is simplified.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a fuel cell stack manifold assembly. Background technique [0002] The fuel cell stack manifold assembly is mainly used as a medium interface. The hydrogen, air and coolant required by the stack flow through the manifold assembly and enter the stack, while the hydrogen, air and coolant after the reaction flow through the manifold The assembly goes back to the stack again. The structure and function of the fuel cell stack manifold assembly have a very important impact on the performance of the stack, the volume specific power of the stack and the fuel cell system. [0003] The fuel cell stack manifold assembly in the prior art only has a simple fluid distribution function, and the function is relatively single, which cannot simplify the fuel cell stack system. Contents of the invention [0004] The object of the present invention is to provide a fuel cell stack manifold as...
