Ceramic Sr(Ce0.95Y0.05)O3-delta was equilibrated at an ambient air (either wet or dry) and Ar-H2 atmospheres. After the step change of gas atmosphere, the equilibration kinetics was monitored by measuring weight change. Fick’s second law was applied to the experimental kinetic data (the in verse method) to obtain the chemical diffusion coefficient, Dchem. The determined Dchem indicates the complex processes in volving creation and transport of both oxygen vacancies and protonic defects in the studied material.
