Abstract

A system (1) for separating CO2 from combustion flue gas by means of molten carbonate fuel cells (MCFC) comprises at least one stack (2) of MCFC cells having an anodic compartment (5) and a cathodic compartment (6), and a treatment device (3) for treating a cathodic exhaust stream exiting from the MCFC stack (2); the device (3) is configured so as to remove H2S from the anodic exhaust and separate from the anodic exhaust a stream containing H2 and substantially free of H2S, and to convey the stream containing H2 to an anodic compartment (21) of a PEM cell unit (18) or to the anodic compartment (5) of the MCFC cell stack (2) and to limit, in the case of recirculation of the anodic exhaust to the anodic compartment (5) of the MCFC cell stack (2) the build-up of N2 in said anodic compartment (5) of the MCFC cell stack (2).
