Poly(aryl piperidinium) Anion Exchange Membrane,15 microns,Mechanically Reinforced

Catalog Number	ACMA00062931
Description	The mechanically reinforced AEMs are manufactured from the functionalized poly(aryl piperidinium) resin material and microporous ePTFE reinforcement in order to yield an AEM with excellent mechanical durability and reduced overall swelling or minimal physical dimension change. Mechanically reinforced membranes can sometimes be called as composite membranes.
Feature	ePTFE-based mechanical reinforcement provides excellent mechanical strength Low swelling and reduced physical dimension change Excellent chemical stability in caustic and acidic environments. Ultra-thin membranes with superb performance for various alkaline fuel cell, alkaline electrolyzer, direct ammonia fuel cells, and other relevant electrochemical technologies.
Notice For Use	For standard alkaline fuel cell / electrolysis applications: Allow the membrane to sit at ambient conditions for 1 hr without a cover sheet before use. To convert the membrane to OH- form, place the membrane in an aqueous solution of 0.5 M NaOH or KOH for 1 h at room temperature. After 1 h, replace the solution with fresh 0.5 M NaOH or KOH and allow the membrane to soak for 1 h at room temperature again. After the two soaks, rinse the membrane with DI water (pH ~ 7). Minimize exposure to ambient air, as the CO2 can exchange back into the membrane causing the membrane to convert back to bicarbonate form. The reaction between CO2 and hydroxide ions is purely chemical and it will readily happen if the OH-form of the membrane is exposed to an environment that has CO2 (such as ambient air, etc.). This conversion can be completely eliminated by simply doing the conversion and testing in a CO2-free drybox environment.
