PROBLEM TO BE SOLVED: To provide a fuel battery cell stack capable of reducing heat conduction member consumption by easily smoothing temperature distribution of fuel battery unit cells.SOLUTION: A fuel battery cell stack 1 comprises a plurality of fuel battery unit cells 2 each including an anode 21, a solid electrolyte layer 22 and a cathode 24. The fuel battery unit cell 2 includes a heat radiation layer 20 that radiates heat of the fuel battery unit cell 2, on an outer surface of the anode 21. The heat radiation layer 20 includes a curved surface part 201 that is curved inwards, on the outer surface thereof. In the fuel battery cell stack 1, a heat conduction member 4 is disposed so as to include a normal concentration part 3 in which normals 202 of the curved surface parts 201 are concentrated. It is preferable that the heat conduction member 4 is supported by a support member 5, and the support member 5 may be a separator to be disposed at a side of te anode 21. The heat conduction member 4 can be formed from a metal material containing copper as a main component.SELECTED DRAWING: Figure 1 |
