Patent ID: 7387650

Claim:
A fuel cell power generation apparatus comprising: a fuel reforming device operable to reform a gas; a fuel cell body including an anode, the fuel cell body being operable to discharge an anode exhaust gas from the anode; raw gas feeding means for feeding into the fuel reforming device at least one raw gas of a burner exhaust gas discharged from a heating burner of the fuel reforming device, exhaust air discharged from a cathode of the fuel cell body, and air from outside the fuel cell power generation apparatus; inert gas formation means for removing oxygen from the at least one raw gas and generating an inert gas, the inert gas formation means including an oxidizable and reducible oxygen adsorbent; and adsorbent reduction means for reducing the oxygen adsorbent by feeding the reformed gas from the fuel reforming device or the anode exhaust gas from the fuel cell body into the oxygen adsorbent of the inert gas formation means, wherein the oxidizable and reducible oxygen adsorbent includes at least one of chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), and zinc (Zn), and the oxygen adsorbent is disposed in at least one of a location between a reforming catalyst layer and a CO conversion catalyst layer provided in the fuel reforming device, a location upstream of the reforming catalyst layer within the fuel reforming device, and a location in the reforming catalyst layer provided in the fuel reforming device.
