Alkaline Fuel Cells Coating Coating Systems

Alkaline Fuel Cells Coating Coating Systems – Catalyst Coating – Cheersonic

All fuel cells are based on the principle that fuel reacts at the anode, and air or oxidant at the cathode of an electrochemical system that produces electric power and some excess heat. In this regard, alkaline-based fuel cells are no different from acidic proton exchange membrane fuel cells (PEMFCs). Historically the first real, “useful” fuel cells were based on liquid alkaline electrolytes and metal electrodes using a form of “zero gap technology” in which the metal electrodes were placed back to back against a thin electrically insulating diaphragm immersed in the liquid electrolyte. The Constitution of modern AFC gas diffusion electrodes (GDEs) typically include multiple PTFE-bonded carbon black (CB) layers, and the prevailing structure is the double-layer electrode structure, embodying a backing material (BM), a gas diffusion layer (GDL), and a catalyst layer (CL).

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’s ultrasonic equipment 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
