A modular modeling strategy is outlined for fuel cells. As a stepping stone towards this modeling paradigm, the cathode-oxidizer assembly of a typical solid oxide fuel cell (SOFC) has been modeled. Various cases were simulated, and the spatial distributions of electric-potential, current, temperature and oxygen concentration have been calculated. An assessment of the results showed some surprising consequences. Detailed resolution of the current density distribution within the cathode has revealed highly non-uniform electrical field thin cathodes. This may have significant consequences concerning distribution of thermal stresses and structural integrity of the fuel cell.
