Spraying of Alkaline Fuel Cells

Spraying of Alkaline Fuel Cells – Thin Film Coating Technology – Cheersonic

Alkaline fuel cells without precious metal catalysts were developed years ago but these traditional alkaline fuel cells required a liquid electrolyte because they lacked a true AAEM and suffered from reliability problems because of the formation of solid carbonate in the presence of CO2. Current research on AAEM fuel cells (AAEMFCs) has shown that these membrane-based systems will not generate solid carbonate because of the absence of any mobile cation. They also mitigate potential corrosion problems by removing the liquid electrolyte. Research in this area has been limited however, and the power densities of AAEMFCs lag behind those of their proton exchange membrane (PEM) counterparts. A major contributor to the low power densities is poor reactant mass transport in the electrodes and this, in turn, is due largely to the lack of available ionomers to use as binders in the electrodes.

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 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：

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
