<P>PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell which can improve efficiency of power generation by making uniform the temperature distribution in a fuel cell stack utilizing cooling action due to endothermic reaction in the reforming while efficiently utilizing heat generation in power generation as a heat source for vapor reforming reaction. <P>SOLUTION: In the solid oxide fuel cell, the fuel cell stack 3 is composed by stacking a power generation cell 7 and a separator 10 alternately, and power generating reaction is generated by supplying fuel gas and oxidizer gas inside the fuel cell stack 3. The reform catalyst tube 30 of the fuel gas filled with hydrocarbon catalyst is arranged around the periphery of the fuel cell stack 3 except at least both ends a, b. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
