abstract = "In this paper, we report the structure, chemical stability and electrical conductivity of Mn, Mo and Y or Sm-codoped CeO2. Ce 0.9-xY0.1MnxO2-δ (x = 5-15\%) (CYMO) were prepared by solid state reactions and co-precipitation at elevated temperatures. Powder X-ray diffraction patterns showed that the samples prepared through wet chemistry route were single-phase fluorite structure over the entire concentration ranges of Mn. However, Mn3O4 was detected in solid state method synthesised CYMO. Among the CYMO investigated in the present work, Ce0.8Y0.1Mn0.1O 2-δ showed the highest total electrical conductivity of 6.1 × 10-3 Scm-1 and 1.5 × 10-2 Scm-1 at 700°C in air and H2, respectively. Mo and Y or Sm-codoped CeO2 were found to be stable in 30 ppm H2S in H2 at 600°C for 12 h, and found to form a single-phase solid solution at elevated temperatures with Y-doped ZrO2 (YSZ) in air.",
