CELL STACK DEVICE, MODULE, AND MODULE HOUSING DEVICE

摘要

[Problem];To provide a cell stack device, module, and module housing device having improved reliability.;[Solution];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 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, 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 members (16) is suppressed and reliability is improved.

主权项

1. A cell stack device comprising:
a cell stack comprising a plurality of cells that are arranged; a manifold fixed to an end of each of the cells; and a sealing member fixing the cells and the manifold, the sealing member comprising a meniscus structure having a concave shape in a cross-section taken in a direction in which the cells are arranged, wherein an angle θ of at least a section of the sealing member disposed between at least two neighboring cells of the cells is 45° or less, where the angle θ is defined by an angle between a vertical line drawn from a leading end portion of the meniscus structure toward the manifold and a straight line connecting the leading end portion and a point located on a profile line of a concave of the meniscus structure and at a midpoint of a height of the leading end portion from a bottom part of the concave.
