Coating technology for proton membrane electrolysis hydrogen production industry

In recent years, the hydrogen energy industry has been developing rapidly as a new generation of clean energy, and it also plays a pivotal role in my country's "carbon neutrality and carbon peak" strategy. One of the main sources of hydrogen is water electrolysis, and electrolysis equipment has also become an important equipment for hydrogen energy storage. The RPS-SONIC ultrasonic spraying system is ideal for spraying carbon-based catalyst slurry onto electrolyte membranes for hydrogen production. The ultrasonic spraying system for PEM proton exchange membrane electrolysis equipment can be configured with a fully automatic loading and unloading and flipping system for double-sided spraying, and can apply different catalyst formulations on each side of the membrane. The durability and repeatability of the coating have been proven to be superior to other coating methods, thereby extending the service life of the PEM proton exchange membrane coating.

RPS-SONIC has extensive expertise in coating preparation for PEM proton exchange membrane electrolysis equipment (such as Nafion), and can accurately control the properties of the catalyst coating to create the most uniform and effective thin film coating for the electrolytic hydrogen production industry.

Benefits of ultrasonic spray nozzle spraying membrane electrode catalyst slurry:

1.Extremely high platinum utilization, up to 90%, has been proven in MEA manufacturing.

2.High strength of porous coating prevents cracking or peeling of catalyst layer.

3.Material consumption can be reduced by up to 50% by reducing overspray and saving expensive catalyst slurry.

4.Precise spray pattern, easy to shape, suitable for a variety of applications.

5.Highly controllable atomization spray, high product consistency.

6.Non-clogging atomization spray, no deviation.

7.Ultra-low flow spraying can be performed, intermittent or continuous.

8.Ultrasonic vibration can continuously disperse and mix solid particles.

9.The ability to coat proton exchange membranes with very little slurry (only 10ml of catalyst slurry is needed to coat multiple proton exchange membranes) is very suitable for the research and development stage.

10.Excellent catalyst coating adhesion, suitable for high-vibration fuel cell applications such as automotive parts.
