Abstract
(EN)
Provided are: a cell stack device comprising a plurality of cells 1, a support member 7b, and a first joining member 7a that joins the cells 1 and the support member 7b; a module; and a module accommodation device. The support member 7b comprises a cracked layer 7b2 that includes a crack 7bc between a support member main body 7b1 and the first joining member 7a. The first joining member 7a comprises a first end section that is in contact with a first gas and a second end section that is in contact with a second gas that differs from the first gas. If the direction perpendicular to the interface between the support member 7b and the joining member 7a is a first direction x and the direction from the first end section toward the second end section of the first joining member 7a is a second direction y, in the second direction y, the maximum length of the crack 7bc is less than the length of the first joining member 7a.

L'invention concerne : un dispositif à empilement de cellules comprenant une pluralité de cellules (1), un élément de support (7b) et un premier élément de liaison (7a) qui relie les cellules (1) et l'élément de support (7b) ; un module ; et un dispositif de logement de module. L'élément de support (7b) comprend une couche fissurée (7b2) qui comprend une fissure (7bc) entre un corps principal de l'élément de support (7b1) et le premier élément de liaison (7a). Le premier élément de liaison (7a) comprend une première section d'extrémité qui est en contact avec un premier gaz et une seconde section d'extrémité qui est en contact avec un second gaz qui diffère du premier gaz. Si la direction perpendiculaire à l'interface entre l'élément de support (7b) et l'élément de liaison (7a) est une première direction x et la direction allant de la première section d'extrémité vers la seconde section d'extrémité du premier élément de liaison (7a) est une seconde direction y, dans la seconde direction y, la longueur maximale de la fissure (7bc) est inférieure à la longueur du premier élément de liaison (7a).
