Description

Technical Field

[0001] This invention relates to the field of ultrasonic spraying equipment technology, specifically to an ultrasonic spraying device. Background Technology

[0002] Membrane electrode assembly (MEA) typically consists of an anion exchange membrane, a catalyst, and carbon paper. The anion exchange membrane is usually sandwiched between two sheets of carbon paper, while the catalyst can be coated on the outside of the anion exchange membrane or embedded between the carbon paper and the anion exchange membrane. Coating the catalyst on the outside of the anion exchange membrane places extremely high demands on the catalyst coating equipment used in fuel cell MEA production.

[0003] Traditional anion exchange membrane ultrasonic spraying equipment mainly consists of an ultrasonic generator, a nozzle assembly, a liquid supply system, a moving platform, and a control system. The ultrasonic generator converts electrical energy into high-frequency vibrations. The nozzle assembly atomizes the liquid material into fine droplets through vibration. The liquid supply system precisely delivers the membrane material solution. The moving platform controls the substrate to move at a uniform speed to ensure a uniform coating. During use, first check the equipment's sealing and wiring connections. Inject the prepared membrane material solution into the liquid supply system. Set the process parameters through the control system, start the equipment, and allow the nozzle and substrate to move relative to each other along a preset trajectory. After spraying is complete, shut down the equipment and clean the nozzle and piping to prevent residual solution from clogging the system.

[0004] In the fabrication of anion exchange membrane fuel cells, ultrasonic spraying technology is widely used for catalyst coating of anion exchange membranes or electrode plates because it can achieve uniform and thin-film deposition of catalysts. However, due to the material properties of anion exchange membranes, such as hydrophilicity and low mechanical strength, the ion conduction requirements of catalyst slurry, and the process characteristics of ultrasonic spraying, membrane wrinkles, ruptures, or local deformations can occur during actual ultrasonic spraying due to airflow impact, temperature changes, or uneven tension. The membrane substrate may not be in close contact with the stage, and displacement may occur due to ultrasonic vibration or airflow during spraying. Summary of the Invention
