Spray Coating of High temperature PEMFCs

Spray Coating of High temperature PEMFCs – Ultrasonic Coating – Cheersonic

There are several compelling technological and commercial reasons for operating H2/air PEM fuel cells at temperatures above 100 ◦C. Rates of electrochemical kinetics are enhanced, water management and cooling is simplifified, useful waste heat can be recovered, and lower quality reformed hydrogen may be used as the fuel. HT-membrane development accounts for ∼90% of the published research in the fifield of HT-PEMFCs. Despite this, the status of membrane development for high temperature/low humidity operation is less than satisfactory. A weakness in the development of HT-PEMFC technology is the defificiency in HT-specifific fuel cell architectures, test station designs, and testing protocols, and an understanding of the underlying fundamental principles behind these areas. The development of HT-specifific PEMFC designs is of key importance that may help mitigate issues of membrane dehydration and MEA degradation.

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.

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
