Anion Exchange Membrane Coatings
Anion Exchange Membrane Coatings – Fuel Cell Coating Systems – Cheersonic
Anion exchange membrane is one of the core components of AEM electrolyzer, and plays two main roles:
- Conducting OH− as an internal channel;
- Isolating hydrogen produced by the cathode and oxygen produced by the anode to avoid dangerous accidents.
AEM plays a vital role in the overall performance and durability of the electrolyzer. The microstructure of AEM is usually composed of different cationic groups and polymer backbones, which give the membrane anion selectivity. Among them, the cationic groups are mostly quaternary ammonium, and the polymer backbone is usually polyarylene ether, polystyrene, polysulfone, polyethersulfone or polyoxyphenylene. Existing studies have shown that the main chain structure of the polymer mainly affects its mechanical and thermal stability, the cationic group mainly affects the ion exchange capacity, ion conductivity and transmission number, and the polymer backbone and cationic group jointly determine its chemical stability. Therefore, the overall structure of the polymer has a certain influence on the degradation mechanism and degradation rate of the membrane.
Currently, AEM water electrolysis technology is at the kilowatt-scale development stage. Globally, several research organizations/institutions are actively working on the development of AEM water electrolyzers. In order to expand the commercial application of this technology, some innovations/improvements are still needed.
Hydrogen production by electrolysis of water is the most advantageous method for producing hydrogen. Utrasonic coating systems are ideal for spraying carbon-based catalyst inks onto electrolyte membranes used for hydrogen generation. This technology can improve the stability and conversion efficiency of the diaphragm in the electrolytic water hydrogen production device. Cheersonic has extensive expertise coating proton exchange membrane electrolyzers, creating uniform, effective coatings possible for electrolysis applications.
Cheersonic ultrasonic coating systems are used in a number of electrolysis coating applications. The high uniformity of catalyst layers and even dispersion of suspended particles results in very high efficiency electrolyzer coatings, either single or double sided.
