Mathematical modeling of mass and charge transport and reaction in a solid oxide fuel cell with mixed ionic conduction

► IDEAL-Cell is an SOFC concept experimentally proven operating in the range 600-700 °C. ► A model for the central membrane, the innovative part of the IDEAL-Cell, is presented. ► Model of transport phenomena and reactions under steady-state in continuum approach. ► Simulations show the strong dependence of results from parameters a priori unknown. ► Optimal porosity, particles radius and cell dimensions obtained by design analysis.
