Hydrogen and Oxygen Chemical Potential Dependence of Electrical Conductivity of SrCe0.95Yb0.05O3-x
In order to clarify the validity of the model of crystal defects that was proposed by the authors to explain the electrochemical properties of the proton conducting oxide, the total electrical conductivity of the sintered sample of SrCe0.95Yb0.05O3-X was measured under the controlled oxygen and hydrogen potentials. The results show that the dependence of conductivity on the potentials is reasonably explained by the reported defect model.
