The preparation and oxygen permeability of Pr0.9AE 0.1Al1-xMxO3 system, where AE=Ca or Sr; M=Co or Fe, have been studied. For Pr0.9Ca0.1Al 1-xFexO3 solid solution having an orthogonal structure, an oxygen flux density of 4.6×10-6 mol cm -2 s-1 was attained for x=0.8 in a methane conversion test at 1000°C, by virtue of the enhancement of p-type conductivity by Fe-doping. In addition, Pr0.9Sr0.1Al0.2Fe 0.8O3 with a membrane thickness of 160 μm exhibited an oxygen flux density of 8.2 × 10-6 mol cm-2 s -1 at 1000°C with the CH4 conversion and CO selectivity of 12% and 93%, respectively.
