Ultrasonic Spray Coating for PEM Fuel Cell

Ultrasonic Spray Coating for PEM Fuel Cell – PEM Spray – Cheersonic

Ultrasound is now a widely used method for catalyst synthesis, catalyst support treatment, catalyst layer fabrication, membrane electrode assembly (MEA) fabrication, and humidifier etc. for fuel cell applications. Among the above mentioned uses, ultrasonic technology has been utilised mainly for MEA fabrication—especially since it has demonstrated the capability to produce ultra-low platinum loadings. The Proton Exchange Membrane Fuel Cell (PEMFC) is a promising power source of the future because of its high power density, high efficiency, lack of harmful emissions, high quality power, scalability and quick start-up. Ultrasound is widely used for many applications. For fuel cell fabrication, it is very commonly used to prepare catalyst inks.

Cheersonic ultrasonic coating systems suitable for R & D, small and medium-sized batch production. UAM4000L is a tabletop system often used in R&D or low volume production for coating Proton Exchange Membrances (PEMs) or other electrolyte materials with metal catalyst inks. These ultra thin materials require several layers of coating to achieve necessary weight gain of inks without deformation of the delicate membranes. Cheersonic has developed coating processes that prvide excellent results with durable, pinhole-free coatings.And because the equipment has the advantage of extremely high liquid utilization, it can greatly reduce research and production costs.

The advantages of Cheersonic ultrasonic coating systems 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).
