Abstract

Pd, Pt and ZrO2-Pt films were prepared by metal organic chemical vapor deposition (MOCVD) as electrodes for zirconia solid electrolyte and their electrochemical properties were examined by impedance spectroscopy. Carbon containing films (Pt-C and Pd-C) consisted of agglomerated fine particles (2-5 nm in diameter) exhibit higher electrode conductivities than that of conventional Pt paste electrodes at temperatures below 873 K. The sintering of the fine particles and/or oxidation of impurity carbon or Pd spoil their electrochemical performance. On the other hand, two-phase ZrO2-Pt films show promise as electrode material for zirconia electrolyte at low temperatures (below 973 K) because of their higher conductivity than Pt paste electrodes and their thermal stability.
