Hydrogen Fuel Cell Catalyst Coating
Hydrogen Fuel Cell Catalyst Coating – Ultrasonic Coating Systems – Cheersonic
Hydrogen can be used as the primary fuel in an internal combustion engine or in a fuel cell. A hydrogen internal combustion engine is similar to that of a gasoline engine, where hydrogen combusts with oxygen in the air and produces expanding hot gases that directly move the physical parts of an engine. The only emissions are water vapor and insignificant amounts of nitrous oxides. The efficiency is small, around 20%.
Polymer electrolyte membrane (PEM) fuel cell produces an electrical current from hydrogen fuel and oxygen in the air. Hydrogen is split into hydrogen ions and electrons by a platinum catalyst at the anode. The PEM allows only the hydrogen ions to pass through to the cathode where these ions react with oxygen to produce water. The electrons travel down a circuit creating an electrical current. The fuel cells are arranged in stacks in order to provide enough electricity to power a vehicle. The use of a fuel cell eliminates the nitrous oxide emissions. Furthermore, the fuel cell is 45-60% efficient.
Hydrogen Fuel Cell’s efficiency attracts more and more people to research it. Cheersonic ultrasonic coating systems suitable for R & D, small and medium-sized batch production. It produce highly durable, uniform, coatings of carbon-based catalyst inks onto both fuel cell and electrolysis processes for proton exchange membrane (PEM) electrolyzers such as Nafion, without deformation of the membrane.
The advantages of ultrasonic spraying include：
1.Excellent stiction “adherence” to PEM; optimal for high vibration fuel cell applications such as automotive parts.
2.Low diversion pressure can reduce waste of overcoating and air pollution
3.Intermittent or continuous operation
4.High transfer efficiency.
5.no blockage
6.Utilization> 95%
7.Corrosion resistant stainless steel and titanium construction
