Coating Of Membrane Electrode Assembly

Coating Of Membrane Electrode Assembly – Automated Coating Systems – Cheersonic

What is less obvious is that the heart and soul of the PEM fuel cell, the membrane electrode assembly (MEA), is also a highly integrated system requiring the expertise of polymer chemists, electrochemists, chemical and mechanical engineers, mathematical modelers, and statisticians to design, fabricate and test an efficient, low cost unit that can compete in the marketplace. In the most complete form, a MEA consists of seven layers: a proton exchange membrane, three-phase anode and cathode catalyst layers, two gas diffusion layers (GDLs), and two sets of sealing gaskets. Each layer of the MEA performs a unique role. However, the MEA is more than a simple collection of these layers because a change in one has an impact on the performance of the others. Rather, the MEA is truly a highly integrated system.

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.
