Solid oxide fuel cells (SOFC) provide energy production at high temperatures. In this study, the effect of operating temperature (873 K–1673 K) and pore diameter (4 μm–16 μm), which are important parameters determining performance solid cells, investigated by exergy analysis. Quadrupling increases activation loss 0.280 V under constant current density. Thermal efficiency, dissipated, entropy efficiency calculated using The power density with increasing temperature. For example, a 3000 A/m2, 45 % from 873 K 3.79 times compared to initial case. At same density, when is 4 μm 10 μm, densities 2659.64 W/m2 2253.46 W/m2, respectively. This explained cell losses low 1000 dissipated 719.85 kW an 973 1030.07 K. 1073 7 diameter, maximum thermal efficiencies 67.77 61.72 %, Increasing 1273 31.55 28.39 decreases causes decrease in efficiency. 30 7000 A/m2 results 5.1 4.64 research examines effects different temperatures diameters detail considering analysis thermodynamic approach, unlike numerical studies concentrated on literature.
