AEM Gas permeability

A procedure for the measurement of gas permeability of an anion exchange membrane (AEM). During the course of the electrochemical reaction, low gas permeation of hydrogen and oxygen through the membrane is crucial to run the process efficiently. The gas permeation rate can be measured using (A) pressure permeation cell, (B) electrochemical monitoring cell, (C) microelectrode and (D) in-situ measurement in MEA. The process relies on a chronoamperometric technique to accurately measure the gas permeation rate across the membrane. The SOP was prepared by Sarah Park.
