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,electronicand mixed (electronic-ionic) conductivity in polymer, ceramic and composite(polymeric-ceramic) membranes. The invention device may work from roomtemperature to 300 °C and the method includes the collection andanalysis ofelectrochemical impedance spectra during cell operation.
