Ultrasonic Spray Coating Machine with 20-200KHz Frequency 1-15W Power and 95% Uniformity for PEM Thin Film

In the manufacturing of proton exchange membrane fuel cells, the ultrasonic precision spraying system perfectly sprays carbon based catalyst ink accurately and uniformly on the electrolyte membrane used for hydrogen production, not only making the membrane electrode surface uniform and the particle dispersion good, but also minimizing excessive spraying, which is a new technology that can save money and produce efficiently.

• Improve coating quality and uniformity, with precision coexisting with higher education
• Ultrasonic spraying has good stability, and the microporous layer and catalytic layer have a three-dimensional pore structure, which is conducive to reducing transmission resistance and forming an effective three-phase reaction zone
• The solution utilization rate can reach over 95%, significantly improving the material utilization rate
• Reduce material waste and air pollution caused by backflow
• Support the application of ultra-low load catalysts
• The carbon based catalyst produced can be uniformly and durably sprayed onto the proton exchange membrane through an ultrasonic atomization system, forming a pinhole free coating that effectively prevents membrane deformation and protects substrate integrity
