PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell stack capable of suppressing damage on the cylindrical cell of a solid oxide fuel cell, while simplifying electrical connection of the cylindrical cells of a plurality of solid oxide fuel cells, and to provide a solid oxide fuel cell module and a solid oxide fuel cell system.SOLUTION: In a solid oxide fuel cell stack (30), a cell assembly (32), a cell bundle (35) and a cell bundle group (36) are constituted of the cylindrical cells of a plurality of solid oxide fuel cells. In the cylindrical cells of a plurality of solid oxide fuel cells constituting each cell assembly (32), adjacent fuel cell layers are fixed by a first conductive paste having conductivity, and connected electrically, and adjacent oxidant gas electrode layers are fixed by a second conductive paste that is porous compared with the first conductive paste, and connected electrically.SELECTED DRAWING: Figure 2 |
