A numerical investigation was conducted on the steady-state electrochemical performance of an anodesupported solid oxide fuel cell (SOFC) with various design parameters and operating conditions. A zerodimensional mathematical model illustrating the electrochemical characteristics of SOFCs was used inthis paper. The simulated results showed good agreement with the experimental data. By using this modelas a simulation, the steady-state electrochemical performances of SOFCs were studied. Additionally,how the electrode and electrolyte thicknesses, triple-phase boundary (TPB) length, operatingtemperature, and pressure affected the SOFC performance was investigated. In addition, the effect of thestructural and operating parameters on overpotentials was studied. Combining the analyses on thestructural and operating parameters, recommendations were provided for optimizing SOFC designs. Thiswork provides systematic suggestions for improving the building of an SOFC electrochemical reactionmechanism model..
