Electrical Properties and Chemical Stability of BaCe_1-_xMo_xO₃_-_δ Proton Conductors

Abstract:

Dense BaCe_1-_xMo_xO_3-_δ ceramics were fabricated by sintering at 1450°C for 7h. All samples were characterized by XRD, SEM. All samples were orthorhombic structure. Electrical conductivities of all samples were measured by AC impedance. Electrical conductivity of Mo-doped samples reaches maximum value when doping content of Mo is 5%, which is one order of magnitude greater than that of BaCeO₃. Chemical stability of BaCe_1-_xMo_xO_3-_δ samples was investigated by immersing samples into the boiling water for 12h. The doping of Mo can partially inhibit the reaction between BaCeO₃ and H₂O.
