20 cm x 28 cm sheets of Sustainion® Alkaline Anion Exchange Membrane B22-50 with PTFE support for easier handleability and greater strength. Presence of the mechanical support increases the mechanical strength and also minimizes swelling or physical dimension change. It is moderately basic (i.e., alkaline) and designed for use with supporting electrolyte. In comparison with Sustainion traditional X37 membrane (which is a self-supporting membrane), the B22-50 Grade T membrane has reduced swelling and reduced metal crossover. It can be used in aqueous and some non-aqueous solvents such as propylene carbonate, and has potential to be used in flow-battery and many other applications.

This anion exchange membrane is supplied in dry from with the counterion being chloride anion. For applications that requires transfer of OH- (or hydroxyl ions), this membrane needs to be converted to the hydroxide form by exposing them to a strong base. It is recommended to soak the membrane in a large bath of 1M KOH for 24 hours in order to convert the membrane from chloride form into the hydroxide form. This activation also helps in strengthening the membrane via crosslinking with KOH as identified by a recent NMR study.

This is a mechanically reinforced anion exchange membrane and the mechanical reinforcement is based on ePTFE (also known as expanded PTFE).
