Abstract:
1. A modular device for measuring ionic, electronic or mixed conductivity of polymeric, ceramics and composites membranes, which permits the simulation of working conditions of different types of membranes such as those used in fuel cells, batteries, pseudo-capacitors and sensors in their working environment, and operating with either gases or liquids, the device comprising: two aluminum plates each containing two compartments, each compartment having an electric heating element incorporated therein; a recess in one of the aluminum plates receiving a thermocouple; two fiberglass or glass seals provided on the plates; two current collectors of stainless steel; a first conductive mesh of graphite surrounded by a first polymeric insulation material that can endure temperatures up to 300° C.; a second conductive mesh of graphite surrounded by a second polymeric insulation material that can endure temperatures up to 300° C.; and a polymer, ceramic or mixed membrane removably positioned between the first and second graphite meshes.
