Electrical conductivity relaxation measurements - water uptake of BaCe0.6Zr0.2Y0.1Tb0.1O3-δ

Description

For Electrical Conductivity Relaxation (ECR) measurements, platinum reversible electrodes were applied in a four-probe arrangement and the BaCe0.6Zr0.2Y0.1Tb0.1O3-δ sample was measured in the ProboStat™ measurement system. The ECR measurements were performed in air in the temperature range of 450-800 ℃ after switching water partial pressure between pH2O = 10^(-5) atm. (DRY) and pH2O = 0.023 atm. (WET).

Each file name contains information on the date of the measurement, temperature, the direction of switch of water partial pressure, and the electrical current used.

The measurements enabled the determination of the chemical surface exchange coefficient of water and the corresponding activation energies for hydration and dehydration in air for the BaCe0.6Zr0.2Y0.1Tb0.1O3-δ sample.
