PROBLEM TO BE SOLVED: To provide a conjugate of a collector member and a fuel battery cell adopting a "configuration where the collector member made of oxide ceramics is buried in a junction material film" and "exfoliation is unlikely to occur on an interface between an outer side surface of an edge of the collector member and the junction material film".SOLUTION: By burying a collector member 300 in a junction material film 80, an outer side surface 300s of an edge of the collector member 300 is covered with a junction material film 80. A ratio (S/T) of a distance (S) of a line corresponding to the outer side surface of the edge of the collector member on a cross section of the collector member in a "thickness direction of the collector member" with respect to a height (T) of the outer side surface 300s of the edge of the collector member covered with the junction material film 80 ranges from 1.2 to 2.0. A ratio of a "total of lengths of a plurality of portions where the outer side surface of the edge of the collector member is brought into contact with the junction material film in the "thickness direction of the collector member" on a line corresponding to the outer side surface of the edge of the collector member on the cross section of the collector member" with respect to T ranges from 10 to 70%.SELECTED DRAWING: Figure 20 |
