Mechanical Characterizations of Boron Oxide Doped Yttria-stabilized Tetragonal Zirconia Electrolyte for High-temperature Solid Oxide Fuel Cell Operated

The aim of this work is to estimate the effect of doping boron oxide to yttria-stabilized tetragonal zirconia (B2O3-Y-TZP) as electrolyte for solid oxide fuel cell operated at high temperature. Nanoindentation has been performed to investigate mechanical properties of doping and pure electrolyte, whereas scanning electron microscopy has been used for morphology studies of the sintered specimens, and X-ray diffraction used for identifying phase and microstructure of electrolyte. The crystallite size of B2O3 doped Y-TZP and Y-TZP estimated to be 137 nm and 895 nm, respectively. The grain size of B2O3 doped Y-TZP and Y-TZP was estimated to be 426 nm and 1225 nm, respectively. B2O3 doped Y-TZP specimens exhibited elastic modulus (E) 115E+15 Pa with yield stress t (N/m2) as much as 327.198 MPa, hardness as much as 948.623 kg/mm2, and fracture strength as much as 3.421 MPa.M1/2.
