Partitioning the Contributions from DC Conductivity and Dielectric Relaxation to the Electrical Response of Ceramics with High Oxygen Ion Mobility: Implication in Fuel Cells and Supercapacitors.

ABSTRACT: The traditional (di)-electrical response of oxygen conducting ceramics is here revisited with the aim of partitioning the contribution from pure DC and pure dielectric components. This work was stimulated by the growing development of ceramic materials in energy-related applications such as fuel cells and supercapacitors. For this purpose, calcia-stabilized zirconia was chosen as a model material and its electrical properties were studied through time- and frequency-domain measurements conducted at various temperatures. The data processing also incorporates the use of Fourier transform and Kramers-Kronig relations in a way that allows integrating both approximations. This general methodology can likewise be applied to other conducting and/or capacitive systems. The dielectric response of t
