AbstractThe paper presents a review of thermal, flow, and material parameters from the perspective of modeling proton‐conducting solid oxide fuel cells (H+SOFC). Comments are offered regarding key parameters selected through research of the literature, featuring mostly material‐related properties of electrolyte and electrodes. Some general relationships are proposed here for the purpose of modeling H+SOFC. The most important parameter is fuel cell operational temperature. Next to the temperature, partial pressures of hydrogen on both sides of H+SOFC impact mainly maximum voltage. The materials from which the fuel cell is built do not directly affect the operation of the fuel cell in the sense that they can be taken as fixed values. Indirectly, their influence can be seen in the resistances, that electrolyte conducts for proton flux and electrodes for electrons. In some cases, double ion/electron conductivity may occur.
