Abstract

The investigation has the aim to study the integration of a molten carbonate fuel cell and a Brayton cycle, that uses supercritical carbon dioxide (S-CO2) as working fluid. The coupling turns out to be feasible achieving 56.25% electrical efficiency at the beginning of cell life, and counteracts the degradation of the MCFC (Molten Carbonate Fuel Cell) over time by converting the extra heat to electricity. The proposed system has been compared with a more conventional system based on the integration of a MCFC system with an ORC (Organic Rankine Cycle) turbine. The boost in electrical efficiency obtained with a Brayton cycle is twice that of a recovery system based on an ORC cycle.
