SOLID ELECTROLYTE FUEL BATTERY CELL STACK, BUNDLE, FUEL CELL, AND MANUFACTURING METHOD OF FUEL CELL STACK

摘要

PROBLEM TO BE SOLVED: To provide a fuel battery cell stack wherein an interconnector 6 of ceramics having lower electric conductivity than general metal is formed to be layered on fuel poles 3a, 3b and a power generating element connecting member 7 is connected thereonto, and so there is no path of a current flowing in the interconnector 6 in the longitudinal direction to reduce the resistance of the interconnector 6.

SOLUTION: The interconnector 6 is formed to be layered on the fuel poles 3a, 3b on a support 2, and solid electrolyte 4 is formed on the fuel poles 3a, 3b in the state of covering both longitudinal ends on the upper face of the interconnector 6. The power generating element connecting member 7 is also provided for connecting an exposed portion of the interconnector 6, which is not covered with the solid electrolyte 4, and an air pole 5 of a power generating element part adjacent thereto.
