Proton Exchange Membrane Coating Processes

Proton Exchange Membrane Coating Processes – Ultrasonic Coating – Cheersonic

H2/air fuel cells based on proton-exchange membranes have many attractive features, including high power density, rapid start-up, high efficiency, which makes them a promising clean energy technology. Great advances have been made in PEM fuel cell development. Catalyst loading has been significantly reduced, power density has been increased, and prototype PEM fuel cell vehicles have been successfully tested on many continents. In spite of these successes, there is strong need to enhance the performance of current PEM fuel cells. Several technical obstacles hinder their widespread commercialization for transportation and stationary application sectors. These include inadequate water and heat management, the intolerance to impurities such as CO, sluggish electrochemical cathode kinetics, and their high cost.

The discovery and development of a high temperature/low humidity membrane is widely considered to play a key role in the progress of HT-PEMFC technology. Cheersonic’s fuel cell catalyst coating systems are uniquely suited for these challenging applications by creating highly uniform, repeatable, and durable coatings. Using the company’s patented ultrasonic spray head technology, it can spray uniformly and efficiently on proton exchange membranes and gas diffusion layers. Uniform catalyst coatings are deposited onto PEM fuel cells, GDLs, electrodes, various electrolyte membranes, and solid oxide fuel cells with suspensions containing carbon black inks, PTFE binder, ceramic slurries, platinum and other precious metals. Other metal alloys, including Platinum, Nickel, Ir, and Ru-based fuel cell catalyst coatings of metal oxide suspensions can be sprayed using ultrasonics for manufacturing PEM fuel cells, polymer electrolyte membrane (PEM) electrolyzer, DMFCs (Direct Methanol Fuel Cells) and SOFCs (Solid Oxide Fuel Cells) to create maximum load and high cell efficiency.

The advantages of Cheersonic’s fuel cell catalyst 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 over coating 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
