PROBLEM TO BE SOLVED: To provide a gas seal structure of a honeycomb structure solid electrolyte fuel cell in which a gas seal part is not exposed to a high temperature even when a SOFC (Solid electrolyte Fuel Cell) is operated at the high temperature. SOLUTION: A long honeycomb structure is integrally formed of a single zirconium material in such a manner that many honeycomb channels 12... having a polygonal cross-section are arranged in all directions. Each of honeycomb channels 12... is constituted of a fuel pole channel line 14..., an air pole channel line 16... and an interconnector channel line 18... to construct a SOFC 10. Moreover, the SOFC 10 is inserted into a furnace wall 24, and a holding plate 26 and a gas supply plate 28 are set on an outside end face of a further to form a gas seal at a temperature lower than room or furnace temperature. |
