Catalyst Solution Spraying

Catalyst Solution Spraying – PEM Fuel Cell Systems – Cheersonic

Extensive research has been carried out on fuel cells worldwide for many years, with particular interest and focus on proton exchange membrane fuel cell (PEMFC) systems. This fuel cell type is the most promising candidate for transportation applications. However, the main drawback with PEM fuel cell is a scarcity of the catalyst, platinum, and issues related to the durability of the components. The presence of macro pores positively affects the fuel cell performance predominantly at higher current densities and at high humidity conditions. How to improve the efficiency of the fuel cell catalyst solution has become a top priority in the development of fuel cells, and among the many spraying methods, ultrasonic spraying stands out.

Cheersonic’s ultrasonic equipment is suitable for spraying catalyst solutions containing carbon black ink suspension, platinum slurry and other precious metal solutions. From R&D to production, our non-clogging technology results in greater control of coating attributes, significant reduction in materials usage, and reduced maintenance and downtime. It can prepare fuel cell proton exchange membrane with excellent performance. It integrates multiple systems such as ultrasonic, dispersion, carrier gas, liquid, heating station, vacuum adsorption, and exhaust emission control.

The advantages of Cheersonic’s ultrasonic equipment include:

1.Highly controllable spray that produces reliable, consistent results.
2.Ultra-low flow rate capabilities, intermittent or continuous.
3.Ultrasonic vibrations continuously break up agglomerated particles and keep them evenly dispersed; maximizing platinum utilization.
4.Corrosion-resistant titanium and stainless steel construction
5.The self-cleaning function of the ultrasonic nozzle prevents clogging.
6.The platform takes up less space.
7.80% reduction in paint consumption
8.The particle diameter is optional which can more flexibly affect the through-hole property of the coating
