PROBLEM TO BE SOLVED: To provide gas treatment equipment and a fuel cell system that are able to use generated heat effectively.SOLUTION: Gas treatment equipment 10 comprises: a combustion catalyst 11 configured to combust combustible gas Gc discharged from a fuel cell device 1 that generates power; an inner cylinder 12 filled with the combustion catalyst 11 and having a heat radiation part 12r that radiates heat to outside; an external wall 13 provided outside the heat radiation part 12r; and a cover plate 14. Between the external surface of the heat radiation part 12r and the internal surface of the external wall 13, the external wall 13 forms a heat receiving channel 18 located upstream of the combustion catalyst 11 in the flowing direction of the combustible gas Gc. The cover plate 14 guides the combustible gas Gc that has flowed in the heat receiving channel 18, into the inner cylinder 12. Therefore, by causing the combustible gas Gc that has received heat radiated from the heat radiation part 12r of the inner cylinder 12 to flow into the inner cylinder 12, radiated heat can be recovered, contributing to energy saving. A fuel cell system 100 comprises the gas treatment equipment 10 and the fuel cell device 1. 【課題】発生した熱を有効利用可能なガス処理装置及び燃料電池システムを提供する。【解決手段】ガス処理装置１０は、発電を行う燃料電池装置１から排出された可燃性ガスＧｃを燃焼させる燃焼触媒１１と、燃焼触媒１１が内部に充填された内筒１２であって、外側へ熱を放散する放熱部１２ｒを有する内筒１２と、放熱部１２ｒよりも外側に設けられた外壁１３と、覆板１４とを備える。外壁１３は、放熱部１２ｒの外表面と外壁１３の内表面との間に、可燃性ガスＧｃの流れ方向において燃焼触媒１１よりも上流に位置する受熱流路１８を形成する。覆板１４は、受熱流路１８を流れた可燃性ガスＧｃを内筒１２の内部に導く。而して、内筒１２の放熱部１２ｒから放出された熱を受熱した可燃性ガスＧｃを内筒１２の内部に流入させることで放熱を回収することができ、省エネルギーに資する。燃料電池システム１００は、ガス処理装置１０と燃料電池装置１とを備える。【選択図】図１
