Abstract
This study numerically investigates thermodynamic losses in solid oxide fuel cell anodes to assess the impact of neglecting microstructure-scale irregularities on predicted overpotential. Two microstructure-scale models are employed: one explicitly accounting for the phase distribution in the electrode and another assuming a continuous medium. Both models incorporate Butler-Volmer reaction kinetics and empirical conductivity relationships. Analysis of 1350 synthetic digital material representations reveals a mean relative overpotential disparity of approximately 6%. The disparity is minimal when the ion-conductor volume fraction exceeds 35% but increases significantly in electrodes with low ion-conductor content. These findings highlight potential drawbacks of continuous electrode models, particularly in microstructures with highly tortuous phases.
