Manufacturing of MEA for fuel cells
Manufacturing of MEA for fuel cells – Ultrasonic Coating – Cheersonic
Research in proton-exchange membrane fuel cells (PEMFC) and direct methanol fuel cells (DMFC) has matured to a point where, in addition to fundamental research in new catalysts, membranes and other materials, manufacturing processes used to make the various components in a fuel cell are drawing much needed attention. One of the key components in a fuel cell is the membrane electrode assembly (MEA) where the actual chemical reactions occur. The porous electrode in the MEA is formed by depositing catalyst ink onto a substrate, which upon drying forms a three dimensional porous structure, which allows for the transport of the fuel and oxidant to the electrode and for the reaction products from the reaction sites on the catalyst surface. If the fuel cell technology is to evolve to a point where it can be commercially viable, the manufacturing costs of the MEA must be driven down, and continuous, automated production technologies developed and optimized, so that volume production can be undertaken.
Cheersonic’s fuel cell catalyst coating systems are uniquely suited for these challenging applications by creating highly uniform, repeatable, and durable coatings. Using the company’s patented ultrasonic spray head technology, it can spray uniformly and efficiently on proton exchange membranes and gas diffusion layers. Uniform catalyst coatings are deposited onto PEM fuel cells, GDLs, electrodes, various electrolyte membranes, and solid oxide fuel cells with suspensions containing carbon black inks, PTFE binder, ceramic slurries, platinum and other precious metals.
1.Excellent stiction “adherence” to PEM; optimal for high vibration fuel cell applications such as automotive parts.
2.Low diversion pressure can reduce waste of overcoating and air pollution
3.Intermittent or continuous operation
4.High transfer efficiency.
5.No blockage
6.Utilization> 95%
7.Corrosion resistant stainless steel and titanium construction
