Zusammenfassung:To provide a system that can efficiently separate and recover carbon dioxide.SOLUTION: A fuel cell system includes an anode exhaust circuit 24 and a carbon dioxide separation and recovery device 60. The anode exhaust circuit 24 has a branch point 42 that branches off halfway into a recycle gas circuit 26 that accepts anode exhaust Ff3 exhausted from an anode 1a of a fuel cell stack 1 and leads it as recycle gas Ff31 to be mixed with raw fuel Ff0 and circulated and a combustion gas circuit 27 that leads it as combustion gas Ff32 used for combustion in a combustor 3. The carbon dioxide separation and recovery device 60 is provided in the combustion gas circuit 27 to separate and recover carbon dioxide contained in the combustion gas Ff32.SELECTED DRAWING: Figure 1 【課題】効率的に二酸化炭素を分離回収できるシステムを提供することを目的とする。【解決手段】燃料電池スタック1のアノード1aから排出されたアノード排気Ff3を受け入れ、原燃料Ff0に混合して循環させるリサイクルガスFf31として導くリサイクルガス回路26と、燃焼器3の燃焼に用いる燃焼用ガスFf32として導く燃焼用ガス回路27とに途中で分岐する分岐点42を有するアノード排気回路24、および燃焼用ガス回路27に設けられ、燃焼用ガスFf32に含まれる二酸化炭素を分離回収する二酸化炭素分離回収装置60、を備えるようにした。【選択図】図1
