PROBLEM TO BE SOLVED: To provide a separator-fitted single fuel cell capable of achieving both prevention of problems such as cracking or the like of a single cell due to the difference between thermal expansion coefficients and prevention of gas leakage.SOLUTION: A separator-fitted single fuel cell of the present invention includes: a plate-shaped separator 12 having an opening 12a; a single fuel cell C arranged on the upper face side of the separator 12 and having a fuel electrode layer 20, a solid electrolyte layer 21 and an air electrode layer 22; a first joining part 30 for joining the single fuel cell C and the separator 12; a plate-shaped ceramic member 32 arranged on the upper face side of the separator 12; and a second joining part 31 for joining the ceramic member 32 and the separator 12. Thus, problems such as cracking or the like of a single cell, which are caused by thermal stress due to the difference between thermal expansion coefficients of members in a joining region J, can be prevented from occurring.SELECTED DRAWING: Figure 3 |
