Effect Of Ultrasonic Spraying On GDL

Effect Of Ultrasonic Spraying On GDL – Ultrasonic Nozzles – Cheersonic

The role of the gas diffusion layer is divided into two main categories, the first regulates all relevant transport processes the transfer of fuel hydrogen and oxidiser oxygen, the discharge of reaction products water and heat dissipation, and the transfer of electrons to the collector; the second acts as a functional interface between the bipolar plate and the catalytic layer, while providing physical support to the electrode layer. The durability of proton exchange membranes used in fuel cells is a major factor in the operating lifetime of fuel cell systems. Durability is a complicated phenomenon; linked to the chemical and mechanical interactions of the fuel cell components.

Cheersonic has developed coating processes that prvide excellent results with durable, pinhole-free coatings. And because the equipment has the advantage of extremely high liquid utilization, it can greatly reduce research and production costs. UAM4000L is a tabletop system often used in R&D or low volume production for coating Proton Exchange Membrances (PEMs) or other electrolyte materials with metal catalyst inks. These ultra thin materials require several layers of coating to achieve necessary weight gain of inks without deformation of the delicate membranes.

The advantages of Cheersonic’s ultrasonic equipment include the following：

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
