ANION EXCHANGE MEMBRANE COATING EQUIPMENT

ANION EXCHANGE MEMBRANE COATING EQUIPMENT

Anion exchange membrane coating equipment is a high-precision membrane processing device specifically designed to uniformly coat or deposit functional layers onto polymer-based membrane surfaces. Currently, this equipment is widely used in various fields, including water electrolysis for hydrogen production, fuel cells, the chlor-alkali industry, and electrodialysis. Not only does it have a wide range of applications and high functionality, it can also be used to prepare high-performance anion exchange membranes (AEMs) to improve their ion selectivity, conductivity, and chemical stability.

What is an anion exchange membrane？

Anion exchange membrane is a class of polymer membranes containing basic active groups, which have selective permeability to anions, also known as ion-selective permeability membranes.

Function:

Selective Transport of Anions: AEM is capable of selectively transporting anions (such as hydroxide ions OH),

allowing for efficient electrochemical processes.

Isolation gases: They can effectively isolate the hydrogen produced by the cathode and the oxygen

produced by the anode, avoiding the danger caused by gas mixing.

Improved Hydrogen Purity: In hydrogen production, AEM ensures that hydroxide ions pass smoothly from

the cathode through the anode, resulting in high-purity hydrogen, which is crucial for fuel cell

Application:

– New-type supercapacitors

– Water treatment industry

– Alkaline anion exchange membrane fuel cells

– Heavy metal recovery

– Flow energy storage batteries

– Hydrometallurgy

– Electrochemical industry

– Chlor-alkali industry
