Non-reinforced Anion Exchange Membrane,Thickness:20𝜇m

Catalog Number	ACMA00062911
Description	This is a non-reinforced Anion Exchange Membrane (AEM) with very low resistance, high selectivity and high stability in pH acidic and basic environment.
Application	Alkaline fuel cells without KOH or at low KOH concentration. This membrane can also be used for other electrochemical applications that require the transfer of anions such as Cl-, Br-, sulfate, and etc.
Storage	Dry form: Storage for long time scale (> 12 month) may be done in dry state (sealed container). Wet form: Storage for short and medium time scale (hours up to several weeks) may be done in unsealed containers in 0.5 - 1.5 wt% NaCl solution or comparable neutral pH electrolytes.
Backing Foil	PET Foil
Color Form	Transparent / Light Brown
Delivery Form	Dry
Dimensional Swelling	< 2 %
Electrical Conductivity	> 5 mS·cm-1
Notice For Use	For standard alkaline fuel cell / electrolysis applications, the membrane should be converted into OH-form by treating it with 0.5 - 1.0 M NaOH or KOH solution: Put the membrane sample in an aqueous solution of 0.5 - 1.0 M NaOH or KOH for at least 24 h at 20°C - 30°C. After rinsing with demineralised water (pH ~ 7) the membrane is ready to use. Use closed container to avoid CO2 contamination (carbonate formation that may affect conductivity). The membrane in OH-form must be stored under wet / humidified and CO2-free conditions, avoid drying out of the membrane in OH-form. Long-term storage in dry conditions should be preferably done in carbonate, Cl- or Br-form.
