A hydrogen fuel cell is a power generation device that directly converts chemical energy of hydrogen and oxygen into electrical energy. The basic principle is the reverse reaction of electrolyzed water, hydrogen and oxygen are supplied to the anode and cathode respectively, and after the hydrogen diffuses out through the anode and reacts with the electrolyte, electrons are released to reach the cathode through an external load. In the air intake system of the hydrogen fuel cell stack, the operating temperature is about 80 ℃, so that the proton exchange membrane in the cell greatly reduces the proton conductivity of the membrane due to the evaporation of water, and the internal resistance of the cell is increased, so that the humidification of the fuel cell membrane needs to be ensured, and the fuel cell can operate in an optimal state. Therefore, it is very important to develop a plastic humidifier assembly for fuel cell air intake system with high performance and high quality
