Preparation of BaCe0.9Yb0.1O3-δ asymmetrical membrane for hydrogen separation at high tempratures
A mixed proton–electron conducting perovskite was synthesized by liquid-citrate method and the corresponding membrane was prepared by pressing followed by sintering. The hydrogen permeability of BaCe0.9Yb0.1O3-δ was studied as a function of temperature and hydrogen partial pressure (PH2) gradient. U...

| description | A mixed proton–electron conducting perovskite was synthesized by liquid-citrate method and the corresponding membrane was prepared by pressing followed by sintering. The hydrogen permeability of BaCe0.9Yb0.1O3-δ was studied as a function of temperature and hydrogen partial pressure (PH2) gradient. Using 100% dry hydrogen at 1173 K, the hydrogen permeation rate of dense membranes (1.63 mm thick) for a mixture of 60% H2/He was 0.000293 mol/(m<sup>2</sup> s). The phase structure of powder was characterized by X-ray diffraction and thermogravimetry (TG). Scanning electron microscopy (SEM) was used to investigate the microstructure of sintered membrane. Activation energy estimated with Arrhenius equation was 29 kJ/mol. |
