      abstract     = {Hydrogen permeation membranes are a key element in
                      improving the energy conversion efficiency and decreasing
                      the greenhouse gas emissions from energy generation. 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.},
