Abstract
A quasi-1D Simulation model was developed to estimate total area-specific resistances for overvoltages (Rtot)and cell voltage by separating gas conversion impedance (GCI) from Overall real-part impedance in high temperature steam electrolysis with a solid oxide cell. Even though GCI is small compared to Rtot, ignoring the GCI will result in higher Simulation Errors at j>0.5 Acm-2. Simulation results attained +-0.3% or better precision against measured cell voltages at 750-850 °C. Furthermore, case studies at 800 °C revealed +-40% local current density Distribution in the cell at 1.0 Acm-2 and 82% steam utilization.
