Phase Transformation of Yttria-Stabilized Zirconia (3 mol% Y2O3) in Fuel Cell Caused by Manganese Diffusion

The diffusion coefficient of Mn in yttria-stabilized zirconia (YSZ, 3 mol%Y2O3) and the structural change in YSZ have been investigated. The diffusion coefficients of Mn were determined to be 7×10−14 m2/s at 1573 K and 2×10−13 m2/s at 1673 K by analyzing the concentration profiles of Mn in YSZ/Mn3O4...
