Spray Coating of AEMFC
Spray Coating of AEMFC – Fuel Cell Coating – Cheersonic
In the case of PEMFCs, high-power density was secured and research and development for commercialization have made significant progress. However, there are technical limitations and high-cost issues for the use of precious metal catalysts including Pt, the durability of catalysts, bipolar plates, and membranes, and the use of hydrogen to ensure system stability. On the contrary, AEMFCs have been used as low-platinum or non-platinum catalysts and have a low activation energy of oxygen reduction reaction, so many studies have been conducted to find alternatives to overcome the problems of PEMFCs in the last decade. AEMFC research and its commercialization must necessarily be realized through extensive collaboration among researchers around the world with expertise in different aspects of fuel cell development.
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.
The advantages of Cheersonic’s fuel cell catalyst coating systems include：
1.Capable of coating PEMs with very small liquid sample sizes (only 10ml of catalyst solution necessary to coat multiple PEMs). Ideal for R&D phase.
2.Ultra-low flow rate capabilities
3.The spray beam is highly controllable for reliable and consistent results.
4.Significantly reduced machine downtime for maintenance
5.Spraying proton exchange membrane with high uniformity and good adhesion
6.Heating plate, vacuum plate or combination of heating plate and vacuum plate
7.Non-clogging atomized spray that does not deviate.
