Abstract

Oxygen permeation measurements were performed on planar membranes of (La_0.8Sr_0.2)_0.95Cr_0.5Fe_0.5O_{3 − δ} (LSCrF)–Sc_0.198Ce_0.012Zr_0.789O_1.90 (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}.
