Flux investigations on composite (La0.8Sr0.2)0.95Cr0.5Fe0.5O3 − δ–Sc0.198Ce0.012Zr0.789O1.90 oxygen transport membranes
Abstract
Oxygen permeation measurements were performed on planar membranes of (La0.8Sr0.2)0.95Cr0.5Fe0.5O3 − δ (LSCrF)–Sc0.198Ce0.012Zr0.789O1.90 (10Sc1CeSZ) with various exchange layers and membrane thicknesses. Addition of a fuel side exchange layer capable of nickel exsolution provided approximately twice the performance compared with no exsolved catalyst for a 300 μm thick membrane at 900 °C. Use of a 20 μm thick membrane with a porous support structure produced a further 7 fold improvement in oxygen flux at 900 °C to yield 3.54 ml cm− 2 min− 1.
