Nowadays there is significant CO2 emission pollution all over the world. European Union even introduced a so-called carbon tax to slow down and prevent global warming. More and more effort has been done to collect and utilize CO2 from power plants. For that reason, the technology as Molten Carbonate Fuel Cell can be used as a CO2 collector. Moreover, besides the power plant itself, Molten Carbonate Fuel Cell produces additional heat and power that also can be used. The technology of the supercritical CO2 cycle is well-known as a powerful and high-efficient cycle for utilizing low- and mid-temperature thermal energy. The cycle seems very promising as the way of increasing the efficiency of MCFC by mean of waste heat utilization. The supercritical CO2 cycle together with the Molten Carbonate Fuel Cell technology are relatively new technologies, currently in R&D state. This paper proposes a 0-D simulation model of combined MCFC-sCO2 cycle aimed to investigate the thermodynamic combination of two technologies and provide a broad variant analysis.
