PEMFCs Spraying

PEMFCs Spraying – Ultrasonic Spray Coating – Cheersonic

In recent years, Proton-Exchange Membrane Fuel Cells (PEMFCs) have been the focus of very intensive researches. Power systems based on proton-exchange membrane fuel cell technology have been the object of increasing attention. This is because they appear very promising for both stationary and mobile applications due to their high-efficiency, low-operating temperatures allowing fast start-up, high-power density, solid electrolytes, long cell and stack lives, low corrosion, and non-polluting emissions into the environment. The advantages of PEMFCs are many, but there are also many challenges in their application. One example is the challenge of spraying. There are many coating methods on the market, but the most suitable method for coating PEMFCs is ultrasonic coating.

Cheersonic ultrasonic coating systems suitable for R & D, small and medium-sized batch production. It produce highly durable, uniform, coatings of carbon-based catalyst inks onto both fuel cell and electrolysis processes for proton exchange membrane (PEM) electrolyzers such as Nafion, without deformation of the membrane. Cheersonic has developed coating processes that prvide excellent results with durable, pinhole-free coatings.And because has the advantage of extremely high liquid utilization, it can greatly reduce research and production costs.

The advantages of coating with cheersonic’s ultrasonic equipment include:

1.Capable of coating PEMs with very small liquid sample sizes (only 10ml of catalyst solution necessary to coat multiple PEMs). Ideal for R&D phase.
2.Ultra-low flow rate capabilities
3.The spray beam is highly controllable for reliable and consistent results.
4.Significantly reduced machine downtime for maintenance
5.Spraying proton exchange membrane with high uniformity and good adhesion
6.Heating plate, vacuum plate or combination of heating plate and vacuum plate
7.Non-clogging atomized spray that does not deviate.
