Gas-water separator applied to hydrogen fuel cell

Abstract

The invention relates to the technical field of gas-water separators, in particular to a gas-water separator applied to a hydrogen fuel cell. Comprising a water storage cavity, an air inlet pipe, a separation cavity shell, an air outlet pipe, a top cover, an exhaust pipe, a first impingement wall separator, a convergent-divergent spray pipe, a second impingement wall separator and a spiral acceleration pipe. The gas-water separator is simple in structure and ingenious in design, gas is firstly accelerated through the convergent-divergent spray pipe, then the centrifugal force of the gas is changed through the special structures of the first wall-impingement separator, the second wall-impingement separator and the spiral accelerating pipe, due to different densities of the gas and liquid, the generated inertia is different, the purpose of gas-water separation is achieved, and the gas-water separator is suitable for large-scale popularization and application. Compared with a traditional gravity type gas-water separator, gas-water separation is achieved by means of different inertia of gas and liquid, the separation effect is good, the water content in a hydrogen loop discharged from a cell stack is effectively reduced, and normal work of the cell stack is guaranteed.

Description

technical field [0001] The invention relates to the technical field of gas-water separators, in particular to a gas-water separator applied to hydrogen fuel cells. Background technique [0002] As a clean energy technology, hydrogen fuel cell is an important part of the sustainable energy system that mankind has been pursuing. In the design and development process of hydrogen fuel cell, water heat management is an important content. Since the battery stack reaction will generate water, if Too much water in the battery stack will cause flooding and affect the performance of the proton exchange membrane. Therefore, it is necessary to properly reduce the water content in the hydrogen circuit discharged from the battery stack to ensure the normal operation of the battery stack; [0003] At present, the common method to reduce the water content in the hydrogen circuit is to use a gas-water separator. The gas-water separator is mainly used for the separation of gas and liquid in t...

Problems solved by technology

[0005] In view of this, the object of the present invention is to provide a gas-water separator applied to hydrogen fuel cells, to solve the problem that most of the existing gas-water separators proposed in the above background technology simply adopt the principle of centrifugal and collision to conduct water separation. Gas separation, the process cannot change the acceleration and centrifugal force of the gas
