AEMs Coating

AEMs Coating – Automated Spray Coating Systems – Cheersonic

Fuel cells are a promising clean energy technology because they are not limited by heat-engine thermodynamics and can operate at low temperature without combustion byproducts. The byproduct of hydrogen/oxygen fuel cells is water. With the supply of fuels, fuel cells can run for infinite time and produce energy. Fuel cells can be used in many fields including stationary power generation, portable equipment, and new energy automobiles. In addition, fuel cells are environmentally friendly, easy to refuel, and have a high-energy efficiency. Polyelectrolyte membranes, namely, anion exchange membranes (AEMs) and proton exchange membranes (PEMs) are a critical component of fuel cells. The benefits of using AEMs in AEMFCs over PEMs in PEMFCs include the use of non-precious catalysts, facile reaction kinetics, and reduced fuel crossover.

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. 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.

The advantages of Cheersonic ultrasonic coating systems include：

1. Excellent stiction “adherence” to PEM; optimal for high vibration fuel cell applications such as automotive parts.
2. Low diversion pressure can reduce waste of overcoating and air pollution
3. Intermittent or continuous operation
4. High transfer efficiency.
5. No blockage
6. Utilization> 95%
7. Corrosion resistant stainless steel and titanium construction
