Thermodynamic performance analysis of a molten carbonate fuel cell at very high current densities

- Both CFD analysis and thermodynamic analysis are implemented.
- For current densities lower than 2500 A m−2, there is no point to pressurize the system.
- Energy and exergy efficiencies are enhanced by a factor of 10% when temperature increases from 883 K to 963 K.
- Both efficiencies initially increase at lower current densities and attain their maximum values at 4000 A m−2.
- Higher operating pressure and temperature decrease the unit cell entropy generation.
