Summary: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
