Resumo
An experimental setup for the evaluation of permeation of gaseous species with the
possibility of simultaneously collecting electrochemical impedance spectroscopy data in disk-shaped
ceramic membranes was designed and assembled. It consists of an alumina sample holder with
thermocouple tips and platinum electrodes located close to both sides of the sample. Water-cooled
inlet and outlet gas connections allowed for the insertion of the sample chamber into a programmable
split tubular furnace. Gas permeation through a ceramic membrane can be monitored with mass
flow controllers, a mass spectrometer, and an electrochemical impedance analyzer. For testing and
data validation, ceramic composite membranes were prepared with the infiltration of molten eutectic
compositions of alkali salts (lithium, sodium, and potassium carbonates) into porous gadolinia-doped
ceria. Values of the alkali salt melting points and the permeation rates of carbon dioxide, in agreement
with reported data, were successfully collected.
