This paper presents a review of different chemical compositions that are used in the production of mixed ionic-electronic conducting membranes with the perovskite structure. In these dense membranes, oxygen from the air is permeated through ionic and electronic processes, and high oxygen permeation fluxes are observed at high temperatures (800-900 ºC). Various membranes were compared for their performance and properties after being synthesized by different methods.

The fabrication of mixed ionic-electronic conducting (MIEC) ceramic-based membranes for oxygen separation has extensively increased in the last three decades as a promising alternative of clean energy delivery. In recent years, the interest on supported MIEC membranes has increased due to their attractive properties such as higher mechanical strength and oxygen flux compared to self-supported membranes. This work presents a literature review on the development of supported MIEC membranes of perovskite structure. The concepts and transport mechanism of those membranes are explained and recent works on supported MIEC membranes are presented. Finally, manufacturing methods of self-supported membranes and their influence on oxygen permeation are discussed.
