Abstract

Calcium doped lanthanum and yttrium manganite electrode materials with oxygen deficiency and low polarization resistance (<;30Ωcm² at 600°C) were tested in new advanced electrochemical sensor for the oxygen measurements. Oxygen sensor with oxide electrodes was showing fast response (t₉₅~5s at 600°C), good reproducibility (±0.04% O₂) and long term stability at different oxygen concentration.
