<P>PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell system from which a rated power generation output can be easily take out with a comparatively simple structure and control even if a fuel cell stack is deteriorated. <P>SOLUTION: This solid oxide fuel cell system includes a fuel reformer 6 to reform a fuel gas, and a solid oxide fuel cell stack 4 having a fuel electrode and an air electrode, and fuel cell power generation reaction is performed between the reformed gas fed to the fuel electrode side from the fuel reformer 6 and air fed to the air electrode side from a blower. In this case, an air distributing and feeding means 42 to feed air flowing toward the air electrode by distributing it is provided, the air distributing and feeding means 42 has a center feed passage part 50 and an end feed passage parts 46, 48, and if the flow of air flowing in the air passage increases, the air distributing and feeding means 42 distributes and feeds air so that the distribution ratio of a distributed air flow distributed and fed to the end feed passage part to a total air flow flowing to the air passage becomes small. <P>COPYRIGHT: (C)2008,JPO&INPIT |
