Abstract A 1‐D electrochemical model for a solid oxide electrolysis cell (SOEC) is developed and validated using published experimental data. The combines thermodynamics, kinetic, ohmic, concentration overpotentials to predict performance. For the anode‐supported SOEC, good agreement obtained between data, with ohmic loss being major contributor cell's total overpotential. Both kinetic losses are less significant due high‐temperature operation. Due dominating performance loss, reducing anode thickness effective in diminishing potential. Overall, this simple can be employed as design tool evaluate component estimate system industrial applications.
