Coating of Thin-Film Functional Layers in SOFC

Coating of Thin-Film Functional Layers in SOFC – Coating Nozzles – Cheersonic

Electrolytic deposition (ELD) and electrophoretic deposition (EPD) are relevant methods for creating functional layers of solid oxide fuel cells. The relevance of the application of electrode position in solid oxide fuel cell (SOFC) technology is associated with the search for new methods to increase the specific power and stability of the cells’ operation, particularly at reduced temperatures.One of the main requirements for SOFC solid electrolyte membranes is that of absolute gas-tightness. Electrodeposition offers such advantages as being able to use simple technological schemes that do not require expensive vacuum equipment and the ability to precisely control the coating thickness by regulating the deposition modes. As this technique is based on the application of an electric field it is especially suitable for deposition on the substrates of complicated shapes, the formation of coatings on selected areas of the cells, the deposition of mono and multilayers, and impregnation of porous electrode substrates.

Ultrasonic coating is a reliable alternative to electrodeposition. 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
