Description

Technical Field

[0001] The utility model relates to the technical field of fuel cell membrane electrodes, and more specifically, to a fuel cell catalyst spraying jig. Background Art

[0002] As the core power generation component of fuel cells, membrane electrodes determine the performance and life of fuel cells, accounting for 50% to 70% of the battery cost. After continuous innovation, membrane electrode preparation technology has gradually transitioned from gas diffusion electrode process to CCM membrane electrode process. The membrane electrode produced by this method directly coats the catalyst layer on both sides of the proton exchange membrane, and then combines it with the gas diffusion layer through hot pressing or cold pasting to form a "CCM" structure membrane electrode, which improves the adhesion between the catalyst layer and the proton exchange membrane, avoiding the low catalyst utilization rate during the use of the previous generation of membrane electrodes.

[0003] In the existing membrane electrode spraying process, the area of ​​the sprayed membrane cannot be completely matched with the size of the vacuum suction cup and the spraying mold. The proton membrane outside the spraying area cannot be fixed by vacuum adsorption, which may cause the sprayed membrane to absorb water during the spraying process and cause swelling and deformation, resulting in a large number of wrinkles on the solvent-dried sprayed membrane. At the same time, after spraying one side, the entire set of spraying jigs must be removed, and then the sprayed membrane must be taken out and reversed to the other side. Finally, the jig components and the sprayed membrane must be installed in sequence, and finally the second side spraying is completed. The spray frame needs to be disassembled and installed more frequently, which increases the operation process and reduces the operation efficiency. Utility Model Content
