Solid oxide electrochemical cells (SOECs) are a promising clean energy technology with the great potential to drive the transition to a sustainable and low-carbon energy future.

This application was developed within the solid oxide fuel cell (SOFC) work plan. It calculates the oxygen surface exchange coefficient (k) and oxygen diffusion coefficient (D) for an oxide sample using electrical conductivity relaxation (ECR) data. The tool also produces a heat map showing the associated uncertainty in fitting the ECR data for given pairs of k and D values, so the user can determine the most likely range of k and D values for the tested values. Multiple datasets for the same material can be plotted to decrease uncertainty. The tool can also simulate ECR curves for inputted kmore » and D values and overlay the simulated curves with experimental data for comparison.« less
