Abstract

AC-conductivity measurements of BaZr0.90Al0.10O 3.δ (where δ describes the number of oxygen ion vacancies per unit cell) in wet and dry N2 have been carried out over the temperature range from 400 to 900 °C. Both atmospheres showed the usual Arrhenius behavior of BaZr0.90Al0.10O 2.95. The proton transport number, tH, was also determined from the conductivity measurements of BaZr0.90Al 0.10O2.95 in wet and dry N2 and takes up values of 0.97 and 0.78 in the temperature range 400-900 °C, respectively.
