NOVELTY - A fuel cell electric power generation system comprises fuel reforming unit which generate reformed gas (26) which modifies fuel containing carbon atom and contains hydrogen and carbon dioxide in molecule, phosphoric acid type fuel cell (9) which has fuel electrode (6) to which reformed gas is supplied, water vapor condensation unit which condense water vapor in fuel electrode exhaust gas discharged from fuel electrode, hydrogen separation storage unit which selectively separate and store hydrogen (57, 58) in exhaust gas and carbon dioxide recovering unit which supplies remaining exhaust gas.    USE - A fuel cell electric power generation system.    ADVANTAGE - Carbon dioxides are efficiently recovered from exhaust gas of fuel cell without reducing electric power generation efficiency of fuel cell. The system contributes to global warming prevention and energy effective usage.    DETAILED DESCRIPTION - A fuel cell electric power generation system comprises fuel reforming unit which generate reformed gas (26) which modifies fuel containing carbon atom and contains hydrogen and carbon dioxide in molecule, phosphoric acid type fuel cell (9) which has fuel electrode (6) to which reformed gas is supplied, water vapor condensation unit which condense water vapor in fuel electrode exhaust gas discharged from fuel electrode, hydrogen separation storage unit which selectively separate and store hydrogen (57, 58) in exhaust gas of water vapor condensation unit, and carbon dioxide recovering unit which supplies remaining exhaust gas with which hydrogen is separated in hydrogen separation storage unit to carbon dioxide storage unit or carbon dioxide processing unit (61). The system produces electric power by fuel cell by supplying fuel and oxidizing agent.
