IEC AEM SOP

Submitted by bill.gutierrez on April 25, 2025

A procedure for measuring the ion exchange capacity (IEC) of an anion exchange membrane (AEM). This is done via a titration method (automated or manual). The SOP was prepared by Yushan Yan, Santiago Rojas-Carbonell, Brian Setzler, Matthew Ueckermann, Kelly M. Meek.

AEM Conductivity

Submitted by bill.gutierrez on April 25, 2025

A procedure for measuring the hydroxide conductivity of an anion exchange membrane (AEM). A four-electrode In-plane conductivity is measured as a function of relative humidity (RH). The SOP was prepared by Yushan Yan, Santiago Rojas-Carbonell, Brian Setzler, Matthew Ueckermann, Kelly Meek.

PEM Thermal Stability

Submitted by bill.gutierrez on April 25, 2025

A procedure for measuring the thermal degradation of proton exchange membranes (PEMs). This is done by thermal gravimetric analysis (TGA) on a dry membrane in SO3H form. The SOP was prepared by Kelly M. Meek.
