In this study, a mixed proton-electron conducting perovskite made from BaCe 0.9 Y 0.1 O 3-d (BCYO) was prepared using a solidestate reaction, whereas a rapidly solidified Zr-based alloy (RSZ) was obtained via a melt-spinning process at a specified cooling rate. Finally, the BCYO/RSZ composite membrane was successfully fabricated by aerosol deposition (AD) at room temperature. The powders and composite membranes were characterized by high-temperature X-ray diffraction (HTXRD), particle size analysis (PSA), scanning electron microscopy (SEM), and X-ray elemental mapping (XRM). The hydrogen permeability of the dense BCYO/RSZ composite membrane was measured with the change of temperature. Under a pure hydrogen atmosphere at 773 Ke1073 K, the BCYO/RSZ composite membrane exhibited higher permeability compared with the sole BCYO membrane over the entire investigated temperature range.

Introduction In recent years, the development of dense ceramic membranes with mixed protonic and electronic conductivities has received considerable attention due to their possible applications in hydrogen-based energy, petrochemical processes, fuel cells, separating membranes, and other technologies [1,2]. In particular, proton transport in multivalent cation-substituted Ba cerate and Sr cerate (BaCe 1-x M x O 3-d , SrCe 1-x M x O 3-d , M: Y, Yb, Tm, Eu) has been widely studied for high temperature hydrogen separation [3e14]. Y-doped Ba cerate materials, BaCe 1-x Y x O 3-d (BCYO), show the highest proton conductivity among the multivalent cation-substituted cerates. However, despite its fast proton conduction, BCYO has not yet been successfully applied for use in a gas separation membrane due to its long-term chemical instability and poor hydrogen permeability under atmosphere containing carbon dioxide or water content [5e8]. In addition, the abovementioned candidate materials for hydrogen separation membranes require thin metal layers on both sides of the membrane or well-distributed metals throughout the whole membrane [15e17]. These metals can * Corresponding author. ** Corresponding author. Tel.: þ82 31 645 1432; fax: þ82 31 645 1488. E-mail addresses: [email protected](J.-H. Kim), [email protected](Y.-M. Kang).

segregation. This indicates that the mixture composed of
BaCe0.9Y0.1O3-d and RSZ powders can be deposited well on ZrO2
porous support using the AD method, satisfying the thickness
and uniformity for H2 separation membranes. Its hydrogen
permeability was studied by measuring the gas permeation as
a function of the temperature. The H2 fluxes increasedwith the
temperature for both systems, and the BCYO/RSZ composite
membrane exhibited higher permeability when compared with
the BCYO membrane over the entire investigated temperature
range under dry conditions. The enhanced hydrogen perme-
ability to the BCYO/RSZ compositemembrane can be attributed
to not only better electrocatalytic activity by the addition melt-
spun Zr based alloy but also suppression of the embrittlement
by the existence of Ba-cerate oxide alloy.
