The solid– state fuel cell is the most widely adopted energy– generating technology in the world for which different oxide– ion conductors of pervoskite structures have been recently investigated for the application in the intermediate temperature– solid oxide fuel cells (IT–SOFCs). In the present work, samples of single substituted BIMEVOX i.e., BIBIVOX (Bi2V1–xBixO5.5–x/2) were prepared in the composition range 0 ≥ x ≥ 0.20 using bottom up sol–gel method. XRPD, FT–IR, DTA, SEM, EDS, and AC impedance spectroscopy were used for the investigation of the correlation between the structural phase stability and oxide– ion performance of the BIBIVOX materials. It has been found that orthorhombic, β, and incommensurate tetragonal, γ′–phases were stabilized at room temperature for compositions with x=0.15 and x=0.20, respectively. The enthalpy of β–γ and γ′–γ transition exhibited a general drop with increasing Bi content. The higher value of conductivity of the substituted compound as compared to the parent compound can be attributed to the increased oxygen vacancies generated as a result of cation doping. AC impedance spectroscopy reveals the fact that this ionic conductivity is mainly due to the grain contribution.
