<P>PROBLEM TO BE SOLVED: To provide a fuel cell system in which discharge of harmful gas during temperature rising is suppressed. <P>SOLUTION: This is a fuel cell power generation system which comprises a fuel cell cell of a cylindrical solid oxide type having a fuel electrode, an air electrode, and an electrolyte, a fuel gas line for supplying a fuel gas to the fuel electrode of this fuel cell, a combustion reducing gas generating means for burning a part of the fuel gas flowing in this fuel gas line, an oxidant gas line for supplying an oxidant gas to the air electrode, a heating means of the oxidant gas flowing in this oxidant gas line, and an air distribution and supply equipment having an air introduction tube that is branched into a branch form for distributing and supplying the oxidant gas supplied from the oxidant gas line to a plurality of cells. In this fuel cell power generation system, a harmful gas detoxifying means is provided at the portion where a mixed gas of a fuel exit gas at the exit of the fuel electrode and an oxidant exit gas at the exit of the air electrode contacts the air distribution and supply part and/or in the vicinity where heat conduction takes place from the air distribution and supply part. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
