Abstract:

For several decades, numerous mixed-conductor materials have been studied as

membrane material or electrodes for SOFC technology. Our study focuses on recent

progress about a better understanding of oxygen transport mechanisms through the ceramic

membrane for air separation. Thus, this work has led to the development of a new setup,

which allows to measure oxygen electrochemical activity on the membrane surface in

working conditions. This original setup provides essential information for the

understanding of the oxygen exchange mechanisms on membrane surface.

Keywords:

ceramic membrane, perovskite, mixed conductor, oxygen semi-permeation, surface exchange mechanisms, bulk diffusion, synthesis.
