PURPOSE: To strengthen joining force, and reduce the cost by containing nickel oxide, iron oxide and titanium oxide in a conductive bond of a power generating film and an electrode connecting corrugated plate in a solid electrolyte fuel cell. CONSTITUTION: In a solid electrolyte fuel cell, an electrode connecting corrugated plate 15 is joined to a power generating film 11 obtained by forming a fuel side electrode 13a and an oxygen side electrode 13b of a mixture of nickel oxide and YSZ on both surfaces of yttria stabilizing zirconia 12 by using a conductive bond 14. At this time, the bond 14 is composed of nickel oxide 70 to 92%, iron oxide 3 to 10% and titanium oxide 5 to 20%. Therefore, separation by inconformity of a thermal expansion coefficient is restrained to the possible minimum level, and joining force is increased, and the cost is reduced. |
