UCA120 Ultrasonic Spray Nozzle for Fuel Cell Catalyst Coating
Product Summary
The UCA120 ultrasonic spray nozzle is engineered for precision coating in fuel cell manufacturing. Operating at a high frequency of 120 kHz, it produces a fine, uniform mist with droplet sizes ranging from 18 to 200 μm. This nozzle ensures consistent catalyst deposition on proton exchange membranes (PEM), supporting the production of high-performance membrane electrode assemblies (MEAs). Its non-clogging design and low-pressure atomization protect delicate membrane materials, making it a reliable choice for both R&D and mass production.
Key Selling Points
- High-Frequency Precision: 120 kHz ultrasonic atomization delivers uniform droplets of 18-200 μm, enabling thin, controlled catalyst layers for enhanced fuel cell efficiency.
- Non-Clogging: The open nozzle design prevents blockages, ensuring uninterrupted operation and minimal maintenance downtime.
- Low-Pressure Safety: Gentle atomization without high-pressure airflow protects fragile PEM membranes from damage, reducing scrap rates.
- Wide Flow Range: Adjustable flow rate from 0.001 to 50 mL/min accommodates various coating speeds and material viscosities.
- Material Compatibility: Constructed from stainless steel and titanium alloy for durability and resistance to corrosive catalyst slurries.
