[0002] Fuel cells have the advantages of being clean, environmentally friendly, and simple in structure, and have been widely used in various fields of our daily life, such as various vehicle systems (such as hydrogen fuel cell buses, logistics vehicles, heavy trucks, sanitation vehicles, etc.), backup power supplies, and household energy storage devices. Generally, an anode plate, a cathode plate, and a membrane electrode constitute a single cell, and multiple single cells are connected in series and parallel to form a fuel cell stack to achieve high voltage and then output the required voltage and power.

[0003] After the fuel cell stack is mass-produced and the stacking work is completed, in order to make the fuel cell stack achieve the best performance state, each single cell group or the membrane electrode assembly of the bipolar plate needs to be activated. The activation process of the fuel cell mainly includes the activation of the catalyst, the wetting of the membrane, the construction of the proton transmission channel, the construction of the electron transmission channel, the construction of the gas-liquid transmission channel, and the optimization process of the electrode structure. Since each produced fuel cell needs to be activated and polarized, the workload of cell activation and performance testing is large. At present, the existing fuel cell activation and polarization operation is inconvenient, the CVM inspection line needs to be connected manually, the fuel cell manifold tee and the pipeline need to be manually disassembled and detected for air tightness, the detection efficiency is low, and there is a large deviation. SUMMARY
