Anion Exchange Membrane,for use in formic acid electrolyzer

Catalog Number	ACMA00062899
Description	The Anion Exchange Membrane has 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.
Application	These membranes can be used in a room temperature formic acid electrolyzer after activation.
Notice For Use	For electrochemical CO2 reduction applications, the anion exchange membrane should be converted to the carbonate or bicarbonate form by treating the membrane initially with 0.1 to 0.5 M KOH or NaOH solution and then with 0.1 to 0.5 M water soluble carbonate or bicarbonate salt solutions (such as potassium carbonate or potassium bicarbonate that is dissolved in de-ionized water or distilled water). Fully submerging the anion exchange membrane into KOH or NaOH solution for 6 to 12 hours and then to the desired carbonate or bicarbonate salt solution for a period of 48-72 hours would be sufficient to fully convert the membrane into either carbonate or bicarbonate form. After rinsing the membrane (which is in the carbonate form) with deionized water or distilled water, it can be assembled inside the electrochemical setup for electrochemical CO2 reduction experiments. While the submersion of the membrane into the KOH or NaOH can be skipped, for such situations, a longer submersion time may be required in order to fully convert the membrane to carbonate or bicarbonate form. Initial conversion to OH- form significantly improves the carbonate ion exchange process due to expanded pore sizes.
