PROBLEM TO BE SOLVED: To provide a fuel battery cell stack which is highly reliable even when it is used at a high temperature for a long period of time.SOLUTION: A fuel battery cell stack 1 has a battery structure 5 in which a plurality of flat plate-like fuel battery single cells 2 are stacked on top of each other via a separator 4. Each of the fuel battery single cells 2 has: an anode 21 to which fuel gas F is introduced; a solid electrolyte layer 22; and a cathode 23 to which oxidant gas O is introduced. A cell surface inner temperature distribution 20 of the fuel battery single cells 2 is designed to be line symmetrical. A binding member 3 for mechanically binding the battery structure 5 in a stacking direction S of the fuel battery single cells 2 is arranged on a symmetric axis L in the cell surface inner temperature distribution 20.SELECTED DRAWING: Figure 4 |
