Perovskites Based on SrCo0.8Fe0.2O3 – δ (SCF) and Ba0.5Sr0.5Co0.8Fe0.2O3 – δ (BSCF) Oxides and Their Application as Membrane Materials and Electrodes for Solid Oxide Fuel Cells

Abstract

Abstract: This review describes perovskites based on SrCo0.8Fe0.2O3 − δ (SCF) and Ba0.5Sr0.5Co0.8Fe0.2O3 − δ (BSCF) oxides, which are thought of as promising materials for catalytic membrane reactors and solid oxide fuel cells (SOFCs). Data on the oxygen permeability of disk-shaped and microtubular membranes based on SCF and BSCF oxides are discussed; special attention is paid to methods used to increase the oxygen permeability of membrane materials and improve their phase/structural stability. The review describes the electrochemical characteristics of promising cathode materials based on SCF and BSCF perovskites and provides a summary of the latest developments.
