The scientific community faces the challenge of identifying and optimizing stable and effective ceramic materials for H2 separation membranes at elevated temperature (400–800 °C) for industrial separations and intensified catalytic reactors. As such, composite materials with nominal composition BaCe0.8Eu0.2O3-δ:Ce0.8Y0.2O2-δ revealed unprecedented H2 permeation levels of 0.4 to 0.61 mL·min−1·cm−2 at 700 °C measured on 500 μm-thick-specimen. A detailed structural and phase study revealed single phase perovskite and fluorite starting materials synthesized via the conventional ceramic route. Strong tendency of Eu to migrate from the perovskite to the fluorite phase was observed at sintering temperature, leading to significant Eu depletion of the proton conducing BaCe0.8Eu0.2O3-δ phase. Composite microstructure was examined prior and after a variety of functional tests, including electrical conductivity, H2-permeation and stability in CO2 containing atmospheres at elevated temperatures, revealing stable material without morphological and structural changes, with segregation-free interfaces and no further diffusive effects between the constituting phases. In this context, dual phase material based on BaCe0.8Eu0.2O3-δ:Ce0.8Y0.2O2-δ represents a very promising candidate for H2 separating membrane in energy- and environmentally-related applications.}, cin = {IEK-1 / PGI-5 / JARA-ENERGY}, ddc = {000}, cid = {I:(DE-Juel1)IEK-1-20101013 / I:(DE-Juel1)PGI-5-20110106 / $I:(DE-82)080011_20140620$}, pnm = {113 - Methods and Concepts for Material Development (POF3-113)}, pid = {G:(DE-HGF)POF3-113}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000387010000001}, pubmed = {pmid:27812011}, doi = {10.1038/srep34773}, url = {https://juser.fz-juelich.de/record/824266}, }
