A fuel cell power generation system, equipped with a fuel reforming device (60) and a fuel cell body (4), includes valves (30a, 32), pipelines (30b, 31), a condenser (34), a pump (35), etc. for feeding a burner exhaust gas (25) (raw gas) discharged from a heating burner (10) of the fuel reforming device (60) into the fuel reforming device (60), and an inert gas formation device (5A) including an oxidizable and reducible oxygen adsorbent (28), which is disposed in the pipelines (30b, 31), and adsorbs oxygen in the burner exhaust gas (25) to remove oxygen from the burner exhaust gas (25) and form an inert gas (40). The fuel cell power generation system can reliably remove residual matter, without leaving it within the fuel reforming device (60), in a simple manner at a low cost and with a compact configuration.

La présente invention concerne un système de génération électrique à pile à combustible qui comprend un dispositif de reformage de combustible (60) et un corps principal (4) de pile à combustible. Ce système comprend aussi des vannes (30a, 32), des passages tubulaires (30b, 3 GAMMA ), un condenseur (34), une pompe (35) destinée à envoyer des gaz d'échappement (25) du brûleur (gaz bruts) évacués d'un brûleur de chauffe (10) du dispositif de reformage de combustible (60). Ce système comprend aussi un dispositif de production (5A) de gaz inerte installé dans les passages tubulaires (30b, 31) pourvu d'un agent d'absorption d'oxygène (28) à capacité de réduction/d'oxydation. Cet agent d'absorption d'oxygène (28) absorbe l'oxygène présent dans les gaz d'échappement (25) du brûleur et retire l'oxygène de ces gaz d'échappement (25) de façon à produire un gaz inerte (40). Des substances résiduelles présentes dans le dispositif de reformage de combustible (60) peuvent être complètement retirées de manière fiable et à faibles coûts avec une structure simple et compacte.
