The finite time thermodynamic indexes including exergy efficiency, exergetic performance coefficient and entropy production rate are derived to evaluate the performance of direct ammonia-fed solid oxide fuel cells from multiple perspectives. Moreover, the effects of operating temperature, operating pressure, fuel utilization, electrolyte thickness and electrode porosity on exergy efficiency and exergetic performance coefficient of the studied direct ammonia-fed solid oxide fuel cells are numerically analyzed. The derived finite time thermodynamic model can be further employed to obtain optimal operating parameters and structural parameters under different application scenarios to guide engineering design and operation control.}, title={Exergetic performance analysis of a direct ammonia-fed solid oxide fuel cell}, type={Article}, URL={http://ochroma.man.poznan.pl/Content/134787/19_AOT-1_2025_Ma_794.pdf}, doi={10.24425/ather.2025.154193}, keywords={DA-SOFC, Finite time thermodynamics, Exergetic performance coefficient, Exergy efficiency}, }
