Advanced oxygen sensor with oxide electrode materials

Calcium doped lanthanum and yttrium manganite electrode materials with oxygen deficiency and low polarization resistance (<;30Ωcm

at 600°C) were tested in new advanced electrochemical sensor for the oxygen measurements. Oxygen sensor with oxide electrodes was showing fast response (t

~5s at 600°C), good reproducibility (±0.04% O
