Why do you have to activate Sustainion membranes?

Sustainion anion exchange membranes from Dioxide Materials are typically supplied in a dry, chloride form supported on a polyethylene terephthalate (PET) liner. They consequently have to be converted to the hydroxide form by exposing them to a strong base. It is recommended that the membrane be soaked in a large bath of 1M KOH for 24–48 hours in order to … Read More
