Catalyst Coated Membrane

Proton exchange membrane (PEM) fuel cells convert hydrogen and oxygen into water and thereby release energy. The heart of a fuel cell is a polymer electrolyte membrane coated with platinum-based catalysts on both sides (catalyst coated membrane, CCM). PEM fuel cells can be used in different mobile and stationary applications, such as power storage, material handling vehicles, light-duty and heavy-duty transport. Within the transportation sector fuel cell electric vehicles partially compete with battery electric vehicles. However, the characteristics of higher driving range and significantly lower refueling times make hydrogen fuel cell vehicles the technology of choice for long range and heavy-duty transportation. Due to the collective commitment to the mission of reducing carbon dioxide emissions, and creating a climate neutral society, the growth of PEM fuel cells is widely foreseen. This will enable worldwide deployment of fuel cell electric vehicles and significant reduction of costs for those.

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.

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.
