Description
Technical Field

Background
The gas-liquid separator is an important component in the hydrogen return module of the proton exchange membrane fuel cell and is used for separating liquid water contained in the hydrogen tail row of the proton exchange membrane fuel cell. During the operation of the pem fuel cell, excessive hydrogen is generally supplied to improve the reaction efficiency, so that unreacted hydrogen is contained in the hydrogen tail row, and the unreacted hydrogen needs to be returned to the stack for reaction through the hydrogen returning module. The hydrogen tail row also contains water vapor and liquid water, and the water content of the gas returned to the electric pile through the hydrogen returning module directly influences the performance of the proton exchange membrane fuel cell, so that the performance of the gas-liquid separator directly influences the performance of the fuel cell.
The gas-liquid separator may be generally classified into a cyclone type gas-liquid separator, a wire mesh type gas-liquid separator, and a corrugated plate type gas-liquid separator according to the separation principle of the gas-liquid separator. The cyclone gas-liquid separator separates liquid drops from the main airflow by using the inertia force and the centrifugal force of the liquid drops in the rotating process; the silk screen type gas-liquid separator enables liquid drops to be adhered to a silk screen under the action of viscous force through a silk screen structure device, so that the liquid drops are separated from wet steam; the corrugated plate type gas-liquid separator increases the contact area of wet steam and a wall surface through the design of a special corrugated plate, so that the wet steam is subjected to frequent speed and direction changes when passing through a flow channel, and liquid drops are separated.
The gas-liquid separator of the fuel cell hydrogen returning module is generally designed in a fixed structure at the present stage, so that the operation requirement of the fuel cell under multiple working conditions is difficult to meet. When the fuel cell operates under a low-load working condition, less water is generated in the electric pile, and under the working condition, if the separation efficiency of the gas-liquid separator is high, the dehydration of the proton exchange membrane can be caused, so that the service life of the proton exchange membrane is shortened; when the fuel cell operates under a high-load working condition, more water is generated in the electric pile, and under the working condition, if the separation efficiency of the gas-liquid separator is low, water blockage of the electric pile can be caused, and the performance of the fuel cell is seriously influenced.
