Electrochemical impedance spectroscopy measurements - conductivity vs. temperature and conductivity vs. oxygen partial pressure for BaCe0.6Zr0.2Y0.2-xFexO3-δ (x = 0.02, 0.05, 0.1)

Description

The dataset consists of two main catalogs consisting of measurement data: of the electrical conductivity of the BaCe0.6Zr0.2Y0.18Fe0.02O3-δ (BCZYFe2), BaCe0.6Zr0.2Y0.15Fe0.05O3-δ (BCZYFe5), and BaCe0.6Zr0.2Y0.1Fe0.1O3-δ (BCZYFe10) samples as a function of temperature and of the electrical conductivity as a function of oxygen partial pressure (pO2). Measurements as a function of temperature were carried out in dry and wet air (pH2O ~ 10^(-5) atm. and pH2O ≈ 0.023 atm., respectively) in the temperature range of 300-800  ℃. Measurements as a function of pO2 were performed at 600 ℃ and 800 ℃ in 5 different gases: nitrogen (N2), 100 ppm of oxygen, 1% of oxygen (1proc), synthetic air, and pure oxygen (O2).

Each file name contains information about the temperature at the moment of the measuerement and, in the case of the measurements in various oxygen partial pressures, the atmosphere in which the measurement was performed. The details about the measurement parameters, such as the AC voltage used, are included in the files themselves.

The collected data enabled the evaluation of activation energies for the electrical conduction mechanism in dry and wet air and the separation of ionic and electronic partial conductivities at 600 ℃ and 800 ℃.
