Abstract
In at least one sealing member (16) disposed between at least two neighboring cells of a plurality of cells (3) in this cell stack device, the angle θ is 45° or less, where the angle θ is defined by an angle between a vertical line drawn from a leading end portion (18) of a meniscus structure toward a manifold (7) and a straight line connecting the leading end part (18) and a point (19) located on a profile line of a concave of the meniscus structure, and at a midpoint of a height of the leading end part (18) from the bottom part (17) of the concave, which makes it possible to obtain a cell stack device in which the occurrence of cracking at bonded parts between the fuel cells (3) and the sealing member (16) is suppressed and reliability is improved.
