Description

Technical Field

[0001] The utility model belongs to the technical field of spraying, and in particular relates to membrane electrode atomization spraying equipment. Background Art

[0002] As the core component of fuel cells, membrane electrode is generally composed of proton exchange membrane, cathode / anode catalyst layer (CL) and gas diffusion layer (GDL). In the membrane electrode preparation process, it is necessary to spray the dispersion (ink) containing catalyst and ionomer on the proton exchange membrane to form a catalyst layer covering membrane (CCM), or spray the ink on the GDL to form a gas diffusion electrode (GDE), or spray the ink on the substrate membrane to form a catalyst layer and then transfer it to the proton exchange membrane or GDL to form CCM or GDE. Existing commercial ultrasonic atomization spray equipment is bulky, and the ultrasonic atomization nozzle unit used is complex and bulky, requiring a large XY axis drive, and the overall system manufacturing cost is high and expensive. At present, in small laboratory research applications, due to the small volume of the catalyst dispersion used in the research and the small spraying area, it is usually sprayed by manually operating a handheld pneumatic spray brush. Handheld spray guns require manual adjustment of the air / liquid opening and closing size, flow rate, start and stop action, spray gun dwell and movement time. It is difficult to accurately control the spray path, spray area and amount of catalyst sprayed. The obtained catalyst layer has low thickness uniformity, poor structural consistency and poor fuel cell performance repeatability. In order to solve the above problems, a utility model patent with patent application number "202320820508.0" discloses a high-precision membrane electrode spraying device, in which the paint is stored in the storage chamber of the spray gun and is brought out by air pressure during spraying.
