Anion Exchange Membrane Coatings for Alkaline Fuel Cells

Anion Exchange Membrane Coatings for Alkaline Fuel Cells – Cheersonic

Any fuel cell is divided into three main components. The electrodes, electrolyte and the external circuit make up a single fuel cell. The aqueous electrolyte used in the AFC is sensitive to the presence of CO2 in the feed stream of air, which is fed across the cathode. The reaction which results, leads to the precipitation of large metal carbonate crystals (K2CO3) which may block pores of the gas diffusion layer on the electrodes resulting in reducing the efficiency of the fuel cell. This phenomenon is called as carbonization or CO2 poisoning. Electrode flooding and electrode drying due to the variation in the amount of electrolyte present is also a challenge, which needs to be tackled to increase the efficiency of the fuel cell.

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.

The advantages of Cheersonic’s ultrasonic equipment include：

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