Ultrasonic Spraying of PEMFCs
Ultrasonic Spraying of PEMFCs – MEA Coating – Cheersonic
The extensive commercialisation of proton exchange membrane fuel cells (PEMFCs) is still limited by several technical challenges, which have been identified as performance, cost, and durability. Especially, actions are required to reduce the membrane electrode assembly (MEA) cost. The membrane’s microstructure can be considered as a fine mesh at either edge with a network of interconnected chambers through its bulk. The membrane allows the transport of protons and water through its structure while inhibiting electron transport and gas permeation. The membrane’s water content influences its properties, specifically ionic conductivity. At each side of the membrane is a catalyst layer, anode and cathode, respectively. An ideal catalyst layer offers a large surface area for the reaction to occur and allows fresh reactants to reach the active site and products to leave without mass transport limitations.
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. 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.
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
