Resumo
The partial substitution of tantalum for cobalt in the SrCoO3 – δ structure is shown to result in suppression of the hexagonal phase formation and stabilization of the high-temperature cubic perovskite phase. Using ex situ high-temperature diffraction method, it is shown that perovskite SrCo0.9Ta0.1O3 – δ (SCT10) does not interact with the Ce0.8Gd0.2O2 – δ electrolyte commonly used in medium-temperature solid-oxide fuel cells. The SrCo0.9Ta0.1O3 – δ perovskite is found to exhibit transport characteristics necessary for being used as the cathodic material in medium-temperature solid-oxide fuel cells. A voltammetric characteristic of microtubular fuel cell with the SCT cathode is shown.
