摘要

PROBLEM TO BE SOLVED: To realize a solid electrolyte fuel cell which has a high strength, can be made in a stack structure easily, and has high generating efficiency. SOLUTION: This solid electrolyte fuel cell A has a square tube form, and made in a structure having a solid electrolyte layer 12 as an intermediate layer, and furnishing an air pole 11 at the inner layer, and a fuel pole 13 at the outer layer. Consequently, the form of the whole body is made in a square tube form, and when they are assembled, the contact with separators 21 is made in a face contact, and the fuel cells A can be assembled easily and stably, corresponding to a flat cell method. And, while the manufacture corresponding to a cylindrical cell method can be made possible, sealing is made easier, and a solid electrolyte fuel cell assembly with high generating efficiency can be realized.
