Nanocomposites based on Pr nickelate-cobaltite are promising materials due to a high oxygen mobility and relatively good chemical stability in working conditions. This work aims at studying performance of membranes based on such nanocomposite. A few PrNi0.5Co0.5O3-δ – Ce0.9 Y0.1O2-δ functional layers, MnFe2O4 – Ce0.9Gd0.1O2-δ buffer layer and Pt/Sm0.15Pr0.15Ce0.35Zr0.3O2-δ + LaNi0.9Pt0.1O3/ Pr0.3Ce0.35Zr0.35O2-δ/Al2O3 catalytic layers were consecutively deposed on Ni/Al foam substrate. The selectivity of methane oxidation into syngas increases with the inlet methane concentration which is typical for such membranes. CH4 conversion is up to 50 % with H2 content in the outlet feed being up to 25 % at 900 °C. H2/CO concentration ratio is >1. Hence, performance characteristics of the membrane demonstrate that these materials are promising for the practical application.
