Ultrasonic Coating for PEM Fuel Cell Electrode Manufacturing
Ultrasonic Coating for PEM Fuel Cell Electrode Manufacturing – Cheersonic
Hydrogen fuel cell is an electrochemical power generation that combine hydrogen and oxygen to produce electricity, with water as byproducts. Fuel cells based on the electrolyte they employ. This classification determines the kind of electrochemical reaction that take place in the cell, the kind catalysts required, the temperature range in which the cell operates, fuel required, and other factors.
In a hydrogen fuel cell, The anode and the cathode are typically porous graphite electrodes coated with platinum, serve as catalyst for the reaction. The anode and cathode are separated by a membrane that is permeable to proton not electrons. The membrane therefore acts as a salt bridge. The fuel (hydrogen) is supplied to the anode, while air (or oxygen), which is the oxidant is supplied to the cathode. The hydrogen fuel cell operate at around 80℃. The gaseous materials consumed are continuously supplied. The high cost and relative scarcity of platinum is one factor that limit the use of hydrogen fuel cell.
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. A uniform film was obtained using ultrasonic coating method. The formation of multiple layers preserves the porosity of the electrode, hinders flooding of the electrode surface during the coating process, and enhances reactant transport during fuel cell operation. Therefore, high-performance, reproducible, and large-area electrodes can be prepared using ultrasonic spraying technology.
The advantages of ultrasonic spraying 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.
