<P>PROBLEM TO BE SOLVED: To secure reliability at a joint part of an isolation separator and a fuel battery cell. <P>SOLUTION: Inner edge of both isolation separators 45, 49 are jointed to upper and lower faces of an outer edge of a cell body 39. That is to say, a lower face of an inner edge of an air electrode side isolation separator 45 is soldered to a joint part 55 of an outer edge of an upper face of solid electrolyte 27 across an entire circumference in an airtight manner. Similarly, an upper face of an inner edge of a fuel electrode side isolation separator 49 is also soldered to a joint part 57 of an outer edge of a lower face of a fuel electrode 25 across an entire circumference. In this manner, by a structure that both isolation separators are jointed from both sides of the cell body 39, even when a stress is applied in a lamination direction of the solid electrolyte fuel battery 1, it is difficult to exfoliate the joint portion. <P>COPYRIGHT: (C)2013,JPO&INPIT |
