This article refers to a Molten Carbonate Fuel Cell (MCFC) system coupled to a plant with a microgas turbine and a heat recovery system for obtaining a small sized hybrid system in co-generative arrangement. MCFC are devices capable of concentrating carbon dioxide (CO2) produced in anode exhaust gases. If they are handled conveniently, it is possible to separate and store the surplus CO2 produced by the plant instead of emitting it into the atmosphere. From the simulation model of the MCFC system, previously developed by the authors, a zero-dimensional and stationary simulation model for the whole hybrid system was formulated and implemented in the same language. By the simulation model of the MCFC system it has been possible to make a parametric analysis of the hybrid plant to find some optimal operating conditions of the fuel cell(s) that maximise the performance of the entire hybrid plant. In addition, the separation of the CO2 surplus produced by the hybrid plant was simulated by the model and then the emissions of carbon monoxide (CO) and nitrogen oxides (NOx) from the same plant were evaluated.

Abstract
This article refers to a Molten Carbonate Fuel Cell (MCFC) system coupled to a plant with a microgas turbine and a heat recovery system for obtaining a small sized hybrid system in co-generative arrangement. MCFC are devices capable of concentrating carbon dioxide (CO2) produced in anode exhaust gases. If they are handled conveniently, it is possible to separate and store the surplus CO2 produced by the plant instead of emitting it into the atmosphere. From the simulation model of the MCFC system, previously developed by the authors, a zero-dimensional and stationary simulation model for the whole hybrid system was formulated and implemented in the same language. By the simulation model of the MCFC system it has been possible to make a parametric analysis of the hybrid plant to find some optimal operating conditions of the fuel cell(s) that maximise the performance of the entire hybrid plant. In addition, the separation of the CO2 surplus produced by the hybrid plant was simulated by the model and then the emissions of carbon monoxide (CO) and nitrogen oxides (NOx) from the same plant were evaluated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
