ABSTRACT:
A method of recovering carbon dioxide gas from the combustion exhaust gas of fossil fuel, using a combustion equipment, wherein fuel gas is supplied to an anode chamber of a molten carbonate fuel cell and oxidizing gas is supplied to a cathode chamber of the fuel cell, the combustion exhaust gas from the combustion equipment is suuplied to the cathode chamber as part of the oxidizaing gas, CO.sub.2 in the combustion exhaust gas is allowed to react with O.sub.2 in the oxidizing gas at the cathode to produce carbonate ion, which is allowed to pass through the electrolyte of the fuel cell and to reach the anode, which the carbonate ion is allowed to react with hydrogen in the fuel gas to produce CO.sub.2 and H.sub.2 O, the anode exhaust gas containing CO.sub.2 and H.sub.2 O generated at the anode is discharged from the anode chamber, H.sub.2 O is separated from the anode discharge gas and high-concentration CO.sub.2 gas is recovered.
