Spraying of AEMs

Spraying of AEMs – Ultrasonic Atomization – Cheersonic

Currently, the main commercially available water electrolysis technologies are proton exchange membrane (PEM) electrolysis and alkaline electrolysis. However, the acidic environment required in PEM electrolysis limits the choice of catalysts to the expensive noble metals, such as platinum, iridium and it oxides. Furthermore, the Nafion-based PEM and titanium stack components directly increase the capital cost of the electrolysis process, hence hindering the wider application of this technology. Recently, researchers have developed an emerging third-generation technology, anion exchange membrane (AEM) water electrolysis, which integrates the benefits of both conventional PEM and alkaline electrolysis.

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 anion exchange membrane (AEM) to create maximum load and high cell efficiency.

The advantages of Cheersonic’ s fuel cell catalyst coating systems include:

1.Ultra-low flow rate capabilities, intermittent or continuous.
2.Ultrasonic vibrations continuously break up agglomerated particles and keep them evenly dispersed; maximizing platinum utilization.
3.Corrosion-resistant titanium and stainless steel construction
4.The platform takes up less space.
5.80% reduction in paint consumption
6.Highly controllable spray that produces reliable, consistent results.
7.The particle diameter is optional which can more flexibly affect the through-hole property of the coating
