Ultrasonic Spray MEA

Ultrasonic Spray MEA – Fuel Cell Membrane Manufacturers – Cheersonic

The Membrane Electrode Assembly (MEA) is the core component of a Proton Exchange Membrane Fuel Cell (PEMFC) and is the site of multi-phase material transfer and electrochemical reactions for energy conversion, involving three-phase interfacial reactions and complex mass and heat transfer processes, directly determining the performance, lifetime and cost of the PEMFC. The gas diffusion layer usually consists of a carbon paper/cloth and a microporous layer loaded on top of it. The cathode gas diffusion layer, cathode catalytic layer, proton exchange membrane, anode catalytic layer and anode gas diffusion layer are commonly referred to as a “five-in-one” MEA, while the microporous layer is included in the assembly as a “seven-in-one” MEA. As the core component of a fuel cell, it is important to improve its performance and lifetime, reduce costs and accelerate the process of large-scale commercialisation of PEMFCs. Therefore, the development of MEAs with simpler preparation process, more stable performance and lower cost is the main direction of research.

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. 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.

Benefits of ultrasonic spraying MEA include：
Very high Platinum utilization proven in MEA fabrication; as high as 90%.
Non-clogging
Low-flow spray reduces spillage and air pollution.
Continuous or intermittent operation possible
Highly porous coatings are extremely durable, preventing cracking or peeling of catalyst layer.
No moving parts to wear out
Minimal maintenance and downtime.
Robust design and materials resist corrosion.
Ultrasonic energy disperses the agglomerated particles, producing a homogeneous coating.
