PEM COATING

Cheersonic’ s fuel cell catalyst coating systems are uniquely suited for these challenging applications by creating highly uniform, repeatable, and durable coatings. Using the company’s patented ultrasonic spray head technology, it can spray uniformly and efficiently on proton exchange membranes and gas diffusion layers. Uniform catalyst coatings are deposited onto PEM fuel cells, GDLs, electrodes, various electrolyte membranes, and solid oxide fuel cells with suspensions containing carbon black inks, PTFE binder, ceramic slurries, platinum and other precious metals. The advantages of Cheersonic’ s fuel cell catalyst coating systems include：

• Full range of ultrasonic nozzles
• Spray patterns are easily shaped for precise coating applications
• Up to 80% reduction in material consumption with reduced overspray, conserving expensive catalyst inks.
• Spray plume can be easily shaped and directed to coat only target area.
• Self-cleaning nozzle design prevents clogging
• Extremely easy-to-control spray provides reliable and consistent results
• Very uniform and durable coating (even on electrolyte substrates).
