Traditional hydrogen separation devices usually adopt a fixed structure, including pretreatment systems such as filtration, condensation, and adsorption, as well as separation units such as membrane separation, pressure swing adsorption, and cryogenic separation. Although these devices can achieve hydrogen separation, they have problems such as poor flexibility, complex maintenance, and insufficient safety. Most traditional devices have a complex structure, and the connections between modules are fixed, making it difficult to quickly adjust and maintain according to specific requirements. In addition, there are certain potential safety hazards in the operation safety of traditional hydrogen separation devices under conditions such as high pressure and high temperature;
