Description

Technical Field

[0001] The present invention relates to the technical field of fuel cells, and in particular to a fuel cell membrane electrode GDL bonding device and method. Background Art

[0002] At present, hydrogen fuel cell vehicles in my country are still in the promotion stage. There is no unified standard for the model and size of fuel cell stacks. The membrane electrodes produced by relevant companies or research institutions are generally characterized by many sizes, small batches and the need for independent customization. The membrane electrode packaging is generally assembled manually by operators or semi-automatically by manual auxiliary equipment. The proton exchange membrane itself is very thin and easily absorbs moisture in the air. It is easy to wrinkle and deform during the assembly process after the protective film is torn off. It requires a high level of operator proficiency, low efficiency and poor consistency of the finished product.

[0003] Therefore, a large number of customized fully automatic standardized packaging equipment came into being. At present, the most commonly used seven-in-one packaging process by equipment manufacturers is sheet-to-sheet assembly, that is, the gas diffusion layer (GDL) of the sheet and the five-in-one of the sheet are loaded through the material box; the GDL is positioned and glued and then overlapped with the five-in-one for flat pressing, so that the seven-in-one product is stacked in the material box after the glue is cured. The advantages of this process are strong compatibility, the ability to produce products with large size differences, and easy changeover; the disadvantages are that the five-in-one incoming material is a sheet, the five-in-one is handled many times, and the CCM is exposed for a long time, which increases the risk of CCM (cumulative purification volume) contamination. In addition, a separator is added between the two five-in-ones, which increases consumables and is also a cost waste in mass production.

[0004] Another seven-in-one packaging method is roll-to-sheet packaging, that is, the five-layer membrane electrode is a coil after hot pressing, the cathode GDL and the anode GDL are cut and formed sheets, which are respectively loaded in a special material box, and the five-in-one unwinding pull tape is used. After positioning and dispensing, the GDL is attached to the five-in-one of the pull tape, and then the water pores and the shape are cut. Finally, the 7-MEA (membrane electrode assembly) finished product is stacked and off the line. The advantages of this process are fast cycle and high production capacity; the disadvantages are poor compatibility, different products cannot be produced on the same line, and it is suitable for single or a few types of products with a certain size.
