<P>PROBLEM TO BE SOLVED: To provide a fuel cell power generation system which is advantageous for improving uniformity of a mixture of an oxidizer gas that flows in the supply passage before the reaction with a humid oxidizer off-gas after the reaction, and which is also advantageous in the aspect of facility. <P>SOLUTION: A supply passage 2 that supplies oxidizer gas to the fuel cell 1, an exhaust passage 3 that makes exhausted oxidizer off-gas flow from an oxidizer electrode of the fuel cell 1, and an off-gas returning passage 4 that communicates the exhaust passage 3 and the supply passage 2, and returns at least a part of the humid oxidizer off-gas exhausted from the fuel cell 1 to the supply passage 2 are provided. A rotational oxidizer off-gas conveyance driving source 5 is installed at the supply passage on the more down stream side of the joining region of the supply passage 2 and the off-gas returning passage 4. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
