SUMMARY In this article the calculation tool further developed and implemented in Matlab language by the authors was used to determine some optimal operating conditions in electrical and thermal or electrical terms for two different types of hybrid systems: molten carbonate fuel cells (MCFC)/gas turbine with their heat recovery system and the hybrid systems operating in these optimal conditions were analyzed. In the heat recovery system, in both cases, a part of the thermal energy of these gases is used to produce the steam necessary for the MCFC system. The remaining thermal energy is used, in one case, for the production of steam at various levels of pressure and temperature, which feeds a steam bottom plant to produce additional electric energy; in the other case, the same thermal energy is used to produce steam for cogenerative use. The heat recovery system was suitably designed according to the circumstances and the performances and the specific CO 2 emissions of the hybrid systems were evaluated.
