How Fuel Cells Work
The principle of fuel cell power generation is similar to that of primary batteries or secondary batteries. Hydrogen oxidation and oxygen reduction reactions occur on both sides of the electrolyte diaphragm, and electrons do work through an external circuit, and the reaction product is water. However, unlike the primary battery, the reactants in the fuel cell are not pre-stored inside the battery, but when the reaction occurs, the fuel gas and the oxidizing gas react and then discharge the product. Therefore, the fuel cell is not an energy storage device but It belongs to the conversion device, and its electrodes and electrolytes do not directly participate in the reaction during the reaction process.
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. Uniform catalyst coatings are deposited onto PEM fuel cells, GDLs, electrodes, various electrolyte membranes, and solid oxide fuel cells with suspensions containing carbon black inks, PTFE binder, ceramic slurries, platinum and other precious metals. Other metal alloys, including Platinum, Nickel, Ir, and Ru-based fuel cell catalyst coatings of metal oxide suspensions can be sprayed using ultrasonics for manufacturing PEM fuel cells, polymer electrolyte membrane (PEM) electrolyzer, DMFCs (Direct Methanol Fuel Cells) and SOFCs (Solid Oxide Fuel Cells) to create maximum load and high cell efficiency.
The advantages of Cheersonic’s ultrasonic equipment include：
1.Very high Platinum utilization proven in MEA fabrication; as high as 90%.
2.Non-clogging
3.Low-flow spray reduces spillage and air pollution.
4.Continuous or intermittent operation possible
5.Highly porous coatings are extremely durable, preventing cracking or peeling of catalyst layer.
6.No moving parts to wear out
7.Minimal maintenance and downtime.
8.Robust design and materials resist corrosion.
9.Ultrasonic energy disperses the agglomerated particles, producing a homogeneous coating.
