Oxygen permeation flux through 10Sc1YSZ-MnCo2O4 asymmetric membranes prepared by two-step sintering
Abstract
Asymmetric membranes based on a dual phase composite consisting of (Y<sub>2</sub>O<sub>3</sub>)<sub>0.01</sub>(Sc<sub>2</sub>O<sub>3</sub>)<sub>0.10</sub>(ZrO<sub>2</sub>)<sub>0.89</sub> (10Sc1YSZ) as ionic conductor and MnCo<sub>2</sub>O<sub>4</sub> as electronic conductor were prepared and characterized with respect to sinterability, microstructure and oxygen transport properties. The composite membranes were prepared by tape casting, lamination and fired in a two-step sintering process. Microstructural analysis showed that a gastight thin membrane layer with the desired ratio of ionic/electronic conducting phases could be fabricated. Oxygen permeation fluxes across the 10SclYSZ/MnCo<sub>2</sub>O<sub>4 </sub>(70/30 vol%) composite membrane were measured from 750 to 940 degrees C using air or pure oxygen as feed gases and N<sub>2 </sub>or CO<sub>2</sub> as sweep gases. Fluxes up to 2.3 ml<sub>N</sub> min<sup>-1</sup> cm<sup>-2</sup> were obtained for the 7 μm thick membrane. A degradation test over 1730 h showed an initial degradation of 21% during the first 1100 h after which stable performance was achieved. The observed degradation is attributed to coarsening of the infiltrated catalyst. (C) 2016 Elsevier B.V. All rights reserved.
