Impedance Studies of the Cell Pt/Ag+ Conducting Glass/Ag Beta Alumina/ Pt

Abstract

The qualitative comparison of the impedance behavior of the three calls platinum/silver(+) conducting glass/ Ag beta alumina; Pt/glass/ Pt and Pt/ beta / Pt leads to the conclusion that the properties of the cell Pt/ glass/ beta / Pt are determined by those of the interfaces Pt/ glass and beta'/ Pt at low and intermediate frequencies. At high frequencies the contributions of the bulk impedances become predominant. A contribution from the impedance of the interface glass/ beta is small with respect to the other contributions. The transfer of the Ag(+) ion from the amorphous glass phase into the crystalline beta alumina is rapid.
