Title: Conductivity and Molecular Dynamics Simulations of (Gd_2O_3)_x(ZrO_2)_(1-x)(x=0.05-0.15) Electrolytes
Abstract:In an attempt to be developed as a electrolyte material for solid oxide fuel cells,AC impedance spectroscopy was employed to study the bulk conductivity of(Gd2O3)x(ZrO2)1-x(x=0.05-0.15) electrolytes.T...In an attempt to be developed as a electrolyte material for solid oxide fuel cells,AC impedance spectroscopy was employed to study the bulk conductivity of(Gd2O3)x(ZrO2)1-x(x=0.05-0.15) electrolytes.The ionic dynamic behaviors of Gd2O3 doped ZrO2 solid electrolytes were also investigated by molecular dynamics simulation.The effect of temperature and Gd2O3 dopant content on the conductivity of materials were simulated and calculated.The results from both experiments and simulations showed that the ionic conductivity was enhanced by ramping temperature,while 8 mol% of Gd2O3 doping concentration tends to have the optimal ionic conductivity.Read More
