That is, as shown in FIG. 3, the module fixing means 20 of the fuel cell device 100 of the present embodiment includes, for example, two first module support members 3, a first connecting member 4, and a second module support member 5. And the second connecting member 6 is a two-stage configuration.

  The first module support member 3 located on the lower side (lower side, in the heat insulating material 11 in FIG. 2) with the first connecting member 4 interposed therebetween is a solid columnar member, as shown in FIG. The lower second end 3b is directly attached to the holding member 1 and its position is fixed. In addition, in the state in which the heat insulating material 11 is placed below the fuel cell module 10 and inside the holding member 1, each first module support member 3 has a through hole 11 a formed in the heat insulating material 11. It is inserted inside. That is, the first module support member 3 also has a function of restricting the displacement of the heat insulating material 11. Moreover, the 1st module support member 3 is not limited to column shape, Cylindrical shape, square pillar shape, etc. can be changed suitably.

  Moreover, the upper part (inner diameter side) of the 1st module support member 3 is formed with the screw hole which opens toward the upper 1st end part 3a (upper surface), such as a bolt inserted into the screw hole. The first end 3a is fastened and fixed to the first connecting member 4 by the screw 3c.

  Similarly to the first module support member 3, the second module support member 5 located on the upper side (upper side) with respect to the first connection member 4 is also a solid columnar member. The second end 3b on the lower side of the second module support member 5 is directly attached to the first connecting member 4 disposed between the second module support member 5 and the position thereof is fixed. . The first connecting member 4 can be fixed by welding or the like, and may be fixed by screwing or the like. Moreover, the 2nd module support member 5 is not limited to column shape similarly to the 1st module support member 3, It can change suitably cylindrical shape, square column shape, etc.

  In addition, a screw hole that opens toward the upper first end portion 5a (upper surface) is formed in the upper portion (inner diameter side) of the second module support member 5 similarly to the first module support member 3. As shown in FIG. 3, the second module support member 5 is connected to the side surface (side wall) of the fuel cell module 10 by a screw 5 c inserted into the screw hole. Fastened and fixed to the member 6.

  In addition, the 1st connection member 4 which connects the 1st module support member 3 and the 2nd module support member 5 to an up-down direction is plate-shaped (flat plate-shaped) components, Comprising: The second module support member 5 has a second end portion 5b (base end portion) fixed thereto, and the first module support member 3 described above is located on both sides of the module support member 5 at positions shifted left and right or front and rear in a plan view as viewed from above. A through hole for inserting the fixing screw 3c is provided.

  Therefore, as shown in FIG. 2 and FIG. 3, in a state where the first module support members 3 are connected to the lower side with the first connection member 4 interposed therebetween, and the second module support member 5 is connected to the upper side. The first module support members 3 and the second module support members 5 are arranged in a “staggered” manner with different positions in plan view. Thereby, the load of the fuel cell module 10 applied to the upper second module support member 5 is dispersed and supported by the two lower first module support members 3.

  In addition, the 2nd connection member 6 connected to the 1st edge part 5a of the 2nd module support member 5 is comprised so that it may protrude from the side surface (side wall) of the fuel cell module 10 in FIG. 2, FIG. However, it is not particularly limited to this shape. Any shape may be used as long as a part of the second module support member 5 has a surface to which the screw 5c or the like disposed on the first end 5a of the second module support member 5 can be fastened. As shown in FIGS. 2 and 3, the second connecting member 6 may have a shape capable of dispersing the load of the fuel cell module 10 applied to the second connecting member 6.

  Next, as shown in the perspective view of FIG. 4, the holding member 1 that supports the load of the fuel cell module 10 has a total of eight, four on each side, in a position corresponding to the vicinity of the end of the fuel cell module 10. A first module support member 3 is attached.

  The heat insulating material 11 placed on the holding member 1 is inserted into the first module support member 3 at a position corresponding to the position of each first module support member 3 fixed on the holding member 1. Through-holes 11a are provided. However, there is no restriction | limiting in particular in the number of the 1st module support members 3, It can change suitably.

  Further, on the inner side of each first module support member 3 in the plane (horizontal) direction, pedestals 2A to 2D that support the heat insulating material 11 placed thereon are provided. Each of these pedestals 2A to 2D is an upward convex shape that protrudes upward from the upper surface of the holding member 1, and is formed by bending a plate-like member, so that a downward concave space is formed in the inside. Has been.

  With this configuration, the pedestals 2 </ b> A to 2 </ b> D support the heat insulating material 11 at a distance (gap) from the upper surface of the holding member 1. Therefore, each base 2A-2D forms the clearance gap (closed space) which improves heat insulation between the heat insulating material 11 and the holding member 1. As shown in FIG. Moreover, the closed space formed in each base 2A-2D also improves the heat insulation between the heat insulating material 11 and the holding member 1. FIG.
