Ultrasonic Nozzle Atomizing For MEA

Ultrasonic Nozzle Atomizing For MEA – Electrode Spray Coating – Cheersonic

In both Solid Polymer Electrolyte (SPE) and Fuel Cell MEAs the principle function of the MEA is to efficiently control the flow of electrons liberated at the electron donating reaction (the anode) to the electron accepting reaction (cathode). This is typically achieved by separating the cathodic reaction from the anodic reaction by using a membrane that conducts protons (H+) only. Electrons are channelled through an external circuit from the anode to the cathode. By controlling the flow and direction of electrons, H2O can either be used to produce H2 and O2 (Electrolysis) or can be produced from H2 and O2 (fuel cell). Since MEAs have no significant capacitance, accumulation of protons or electrons at either surface of the MEA is negligible. The true potential of the MEA is not only determined by the properties of the individual components but mainly by the MEA production method. Among them, the preparation of the anode and cathode catalytic layer on the proton exchange membrane layer is the core production step, and the quality of the formation of the anode and cathode catalytic layer directly affects the overall power generation, performance, and lifespan of the fuel cell. The currently highly promising method for preparing membrane electrodes is ultrasonic spraying.

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.

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.Up to 80% reduction in paint consumption.
8.The particle diameter is optional which can more flexibly affect the through-hole property of the coating.
