Selection of oxygen permeation models for different mixed ionic‐electronic conducting membranes

“…24,25 Membrane configurations were also broadly studied in recent years, especially on single-channel and multichannel hollow fiber membranes. 4,26,27 At the same time, some researchers are trying to disclose the oxygen permeation mechanism and build permeation models to describe the oxygen permeation process. [28][29][30][31][32][33][34][35] With the help of a proper oxygen permeation model, the oxygen exchange kinetics, diffusion kinetics and degradation mechanism can be well understood for MIEC membranes.…”

“…At present, research activities related to MIEC membranes for oxygen separation are mainly focused on finding materials with high oxygen permeation flux and high stability, exploring methods stabilized membrane at intermediate‐low temperature, and using membranes as reactors for the purpose of process intensification . Membrane configurations were also broadly studied in recent years, especially on single‐channel and multichannel hollow fiber membranes . At the same time, some researchers are trying to disclose the oxygen permeation mechanism and build permeation models to describe the oxygen permeation process .…”
