Problems solved by technology

[0005] Through the above analysis, the problems and defects of the existing technology are: inaccurate positioning; easy to cause relative displacement between the membrane electrode and the bipolar plate, so that the fluid distribution between the single cells of the battery pack is uneven; the pressure in the process of packaging the battery is controllable Poor performance, easy to cause damage to the membrane electrode and bipolar plate of the single cell; manual operation, low production efficiency, poor assembly quality, affect the performance of the battery
Therefore, the existing fuel cell assembly technology and equipment cannot meet the needs of high-efficiency, high-quality, intelligent assembly and production of single cells and battery packs. It is necessary to develop a new type of intelligent fuel cell assembly machine that is efficient, high-quality, and intelligent. Assembling and manufacturing single cells and battery packs is of great significance to improving production efficiency, ensuring the performance of single cells and battery packs, and promoting the commercial application of fuel cells

Embodiment 1

[0067] Membrane electrode assembly assembly process:

[0068] The membrane electrode assembly is composed of the upper fixed pair 13 of the membrane electrode, the membrane electrode 14 and the lower fixed pair 15 of the membrane electrode. The specific structures of the upper fixed pair 13 and the lower fixed pair 14 of the membrane electrode are as follows: Figure 4 and Figure 5 shown. Before assembling the membrane electrode assembly, first set the working temperature, working pressure, working speed and working time through the display control system 9. According to different technical requirements, the working time is set to 3-10 minutes, and the working temperature is set to 60-80°C. The working pressure is set to 0.4-0.6Mp, and the working speed is set to 0.5-10mm / s. When assembling, first apply sealant to the fronts of the upper fixing pair 13 and 15 of the membrane electrode, put the reverse side of the lower fixing pair 15 of the membrane electrode down on the ra...
