Fuel Cell Catalyst Coating

Fuel cell working principle
Although the name “fuel” is included in the fuel cell name, and hydrogen can also burn with oxygen violently, fuel cells do not use combustion to obtain energy, but use the charge transfer in the chemical reaction between hydrogen and oxygen to form an electric current. The most critical technology in this process is the use of a special “electrolyte film” to split hydrogen. The entire process can be understood as mosquitoes cannot pass through the screen window, but smaller dust can … Electrolyte film is also the most difficult in the field of fuel cells Overcoming technical barriers.

Ultrasonic spray deposition for production of fuel cells electrolyte film
Compared with conventional coating technology, fuel cell carbon catalyst ink films made with ultrasonic nozzles have several key advantages: the largest surface area of platinum exposed and uniformly dispersed particles, the largest film thickness uniformity, and the platinum mesh density to produce the most A large amount of platinum can be used for airflows where there are no inconsistent hot spots or low catalyst density areas, and the film characteristics have maximum repeatability without degrading process performance. The platinum film deposited by the Cheersonic ultrasonic spraying method has an efficiency of more than 90% to optimize the coating efficiency, and the repeatability is ± 1%.
