Modular device to measure ionic, electronic and mixed conductivity in polymeric and ceramic membranes

摘要

This invention consists in a device and a method to determine the ionic, electronic and mixed (electronic-ionic) conductivity in polymer, ceramic and composite (polymeric-ceramic) membranes. The invention device may work from room temperature to 300° C. and the method includes the collection and analysis of electrochemical impedance spectra during cell operation.
