Ultrasonic Spray System for PEMDMFC

Ultrasonic Spray System for PEMDMFC – Ultrsonic Nozzle – Cheersonic

With the increasing development of fuel cells, there is an increasing amount of research into PEMDMFC, but PEMDMFC is not yet widely used. Currently, there are two major obstacles inhibiting the application of PEMDMFC, namely, the low activity of methanol oxidation catalysts and the phenomenon of methanol crossover through the polymer electrolyte membrane from the anode to cathode side. Efforts were expended in developing new anode catalysts and, to some extent, methanol impermeable membranes. Nafion, perfluorosulfonic acid polymers, are the most commonly fuel cell membranes. However, a methanol transport through the membrane was observed. Crossover causes lost of fuel at the anode and performance lost at the cathode due to consumption of oxygen and catalyst poisoning. If these problems can be effectively addressed, the direct methanol fuel cell will offer the best chance for fuel cell commercialization in private vehicles.

Cheersonic’s ultrasonic equipment is suitable for spraying catalyst solutions containing carbon black ink suspension, platinum slurry and other precious metal solutions. From R&D to production, our non-clogging technology results in greater control of coating attributes, significant reduction in materials usage, and reduced maintenance and downtime. It can prepare fuel cell proton exchange membrane with excellent performance. It integrates multiple systems such as ultrasonic, dispersion, carrier gas, liquid, heating station, vacuum adsorption, and exhaust emission control.

The advantages of Cheersonic’s ultrasonic equipment include the following：

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