Download or read book Electrochemical Performance and Stability of Ba₀.₅Sr₀.₅Co₀.₈Fe₀.₂O₃₋δ for Oxygen Transport Membranes written by Niedrig, Christian and published by KIT Scientific Publishing. This book was released on 2015-12-23 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mixed ionic-electronic conducting (MIEC) ceramics as oxygen transport membranes (OTMs) can provide high oxygen permeation rates at comparably low energy demands. For this purpose, Ba?.?Sr?.?Co?.?Fe?.?O??? (BSCF) shows the best performance under ideal operating conditions. Thermal and chemical stability investigations, electrical behavior ?(T,pO?,t), and oxygen exchange parameter extraction by means of electrical conductivity relaxation resulted in a far better understanding of the BSCF system.
