120Khz Ultrasonic Fuel Cell Spraying Coating Gathering Together Nozzle is an ultrasonic atomizing nozzle with small spray width (2-20mm) . The ultrasonic atomization nozzle technology is adopted, and the special contraction flow channel design will uniformly and centrally distribute the carrier gas, so that the ultrasonic atomized liquid mist is in the form of concentrated spray, thus reducing the spray area of the ultrasonic nozzle. Due to the small spraying width of the centralized ultrasonic nozzle, it is mainly suitable for various small and medium-sized spraying applications, complementing FUNSONIC FocusMist spraying ultrasonic nozzle, and can be almost suitable for all different flat spraying requirements.
advantages
1. The coating is ultra-thin and uniformly applied, with controllable droplet size of 5-30 μ m and soft atomization without high pressure impact. It can accurately prepare 2-8 μ m ultra-thin catalytic layers
2. The utilization rate of the slurry is extremely high, with no high-pressure overspray or rebound splashing caused by ultrasound. The utilization rate of the slurry is 92% to 97%, reducing the loss of Pt/C precious metals
3. The microstructure of the catalytic layer is excellent, the formed pore structure is reasonable, the three-phase interface is rich, and the Pt utilization rate is improved
4. Low temperature and mild film formation, no high pressure impact to damage proton membranes, improved mass production yield, indirectly reducing unit platinum consumption

FAQ
Q: What is the effect of solution viscosity on nozzle frequency during ultrasonic spraying?
A: High-frequency nozzles are typically used for low-viscosity coatings. This is because high-frequency vibration generates greater shear force, enabling effective dispersion and spraying of low-viscosity coatings. Conversely, applying excessively high frequencies to high-viscosity coatings may cause the material to exit the nozzle too rapidly, leading to inadequate dispersion.
Q: What is the effect of solution viscosity on amplitude?
A: The setting of amplitude is also closely related to the viscosity of the coating. For high-viscosity coatings, it is generally necessary to increase the amplitude. High-amplitude vibration can deliver higher energy, facilitating the dispersion and spraying of high-viscosity coatings. Conversely, excessive amplitude for low-viscosity coatings may lead to over-dispersion or loss of control during spraying.
Q: What is the reason for the easy precipitation of Pt/C (platinum carbon) slurry?
A: Pt/C (platinum carbon) slurry is the core raw material of PEM catalytic layer, with a Pt particle density of ≈ 21.4g/cm ³ and a carbon carrier XC-72 of ≈ 1.8g/cm ³. The solid-liquid density difference is extremely large, and it is prone to gravity settling according to Stokes' law.
Q: What is the effect of Pt/C slurry settling on PEM membrane?
A: The settling of Pt/C (platinum carbon) slurry directly causes fluctuations in the platinum loading of the catalytic layer, imbalance of the three-phase interface, deterioration of single-cell consistency, and waste of platinum raw materials
