The MCFC working principle can be seen in Fig. 1 [14].The CO 2 separation is due to the electrochemical reactions that take place inside the cell: CO 3 −2 ions transit through the electrolyte and transport CO 2 straight from cathode to anode side. A flue gas sent to the cathode inlet would leave the cathode outlet with a CO 2 reduction up to 85% …
