Sustainion® X37-50 Grade RT Membrane

Sustainion® Anion Exchange Membrane with a dry thickness at above 50 microns. They are moderately basic and designed for use with supporting electrolyte. Dioxide Materials has optimized them for use in alkaline water electrolyzers and in CO2 electrolyzers as described in Kutz et al. Energy Technology 5, 929-936 (2017) and Masel et al. ECS Transactions, 75 (14) 1143-1146 (2016).
See also patents 9,370,773, 9,481,939.

The membranes are shipped with an ethylene glycol plasticizer to prevent cracking. The plasticizer is designed to wash out during activation.

Sustainion® X37-FA Membrane

Sustainion® Anion Exchange Membrane with a dry thickness of 50 microns. They are moderately basic and designed for use with supporting electrolyte.

These are special membranes with lower crossover, which show superior performance in our electrolyzer to convert CO2 to formic acid. The X37-FA membranes should be activated for 12 hours in 1 M KOH at room temperature before use.

Note: these membranes can be used in a room temperature formic acid electrolyzer after activation.

Sustainion® Alkaline Anion Exchange Membrane X37-50 grade T

20 cm, x 28 cm sheets of Sustainion® Alkaline Anion Exchange Membrane with PTFE support for easier handleability and greater strength. It is moderately basic and designed for use with supporting electrolyte. Dioxide Materials has optimized it for use in anion exchange membrane water electrolyzers electrolyzers as described in Masel et al. ECS Transactions, 75 (14) 1143-1146 (2016).
See also patents 9,370,773, 9,481,939.

The anion membranes are supplied in dry-chloride form. They consequently have to be converted to the hydroxide form by exposing them to a strong base. Dioxide Materials recommends soaking the membrane in a large bath of 1M KOH for 24 - 48 hours in order to convert the membrane 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 [19]. Furthermore, during this process the membrane swells.

Note:  The membrane is a sandwich structure with a thin porous PTFE layer coated with sustainion 37 on both sides. The PTFE decreases the transport of water in the membrane so they are less efficient in CO2 electrolyzers.

Sustainion® Alkaline Anion Exchange Membrane E30-50 grade T

20 cm x 28 cm sheets of Sustainion® Alkaline Anion Exchange Membrane with PTFE support for easier handleability and greater strength. It is moderately basic and designed for use with supporting electrolyte. In comparison with our traditional X37 membrane, the E30 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.

The anion membranes are supplied in dry-chloride form. They consequently have to be converted to the hydroxide form by exposing them to a strong base. Dioxide Materials recommends soaking the membrane in a large bath of 1M KOH for 24 hours in order to convert the membrane 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.
