Ultrasonic Spray System For PEMFC Coating

Ultrasonic Spray System For PEMFC Coating – Cheersonic

PEMFC, as the most authoritative new energy power generation device in the low temperature field, it now plays an increasingly important role in the mobile field. How to improve the cost return rate and power generation efficiency of new energy is the core of the development of PEMFC. MEA is as a key component of PEMFC, increased research effort is being focused towards scalable deposition techniques such as blade-coating, slot-die coating, inkjet printing and spray coating.

Cheersonic focuses on the ultrasonic spray coating nearly twenty years. We provide a series of standard machines but also customized solution for energy industry such as fuel cell, solar cell and so on. In the various liquid handling ultrasonic spraying cases at home and abroad, taking fuel cells as an example, the substrates we spray are generally divided into three types: Nafion membrane, carbon cloth, and carbon paper. PEM directly affect the performance and life of battery. As an electrolyte, it conducts protons and isolates the reaction gas. Nafion membrane as the water-based acid polymer, is good as high conductive under high humidity conditions, high mechanical strength and good chemical stability at low temperature.

Cheersonic ultrasonic spraying system is very suitable for spraying small area of Nafion membrane substrate. The nozzle is waterproof, anti-corrosion and non-clogging for uniform coating, reducing the downtime in critical processes. Low pressure air/gas is used to focus the spray into very thin lines in very low volume applications especially for R&D. The continuous ultrasonic vibration in the nozzle and the frequency of 50kHz can maximize the consistency of the liquid characteristics during the spraying process especially for some solutions with relatively low viscosity. Besides ultrasonic vibrations continuously break up agglomeration to maximize catalysts utilization. Since Nafion membrane has the characteristics of swelling easily when absorbed by water, ultrasonic nozzle creates the thinnest, most sharply defined lines of all air shaping systems, which can accurately spray uniformly in a short time.

In a word, the ultrasonic spraying system is friendly to operation for small area precision spraying. We have carried out diversified applications of ultrasonic spraying in actual application. Ultrasonic spraying system can be embedded in large-scale equipment for coordinated use. In order to cope with the ever-expanding new application fields of various liquids, Cheersonic ultrasonic spray system is willing to actively cooperate with various industries to promote new development.
