Oxygen permeation and thermo-chemical stability of oxygen separation membrane materials for the oxyfuel process
… which consists in the burning of coal in an oxygen-rich atmosphere to produce a flue gas highly concentrated in CO2, is a technology considered for zero CO2 emission coal-fired power plants. The production of this O2-rich combustion gas from air can be carried out using high purity oxygen …

An electrochemical study on the ionic conductivity of ceramic electrolyte La1-2SrxCo3-yMyO3-sigma oxide and its Pd/Ag compsites
… studied the electrochemical properties of the oxygen ceramic electrolytes of La1-xSrxCo1-yMyO3-d perovskite-type oxides that possess excellent electronic and oxygen anionic conductivity. Such mixed-conductivity is the essential property that the cathode material of solid oxide fuel cell (SOFC) …

Strukturelle und elektronische Untersuchungen am hoch sauerstoffdefizitären Mischleiter Ba x Sr 1-x Co 0,8 Fe 0,2 O 3-delta (BSCF)
… materials, such as superconductivity and high oxygen permeability, whereas these properties are also highly dependent on the surrounding oxygen partial pressure and temperature. In this family of materials, BSCF stands out as it accommodates an extremely high oxygen nonstoichiometry delta which …

Oxygen transport in Ba(Fe,Co,Zr)O 3 - delta membranes
… is measured as a function of temperature and oxygen activity by TG. Very high nonstoichiometry (delta0=0.78 at a(O2)=1) is determined at 1273 K. From the nonstoichiometry of Ba(Fe,Co,Zr)O3-delta;, exponent n (n=-0.01) in Cv=C0v•a(O2)n, thermodynamic factor (gamma=140) and activation energy for …
