- the vibration of the fuel cell case 300 and the fuel cell 200 can be realized, for example, by vibrating the fuel cell case 300 in which the fuel cell 200 is accommodated using a vibration generator.
- Supplying the small piece into the fuel cell case 300 can be realized by opening the cover 112b of the small piece supply part 112 and supplying the small piece to the cylindrical part 112a.

- the diameter of the small piece is less than 1/2 of the variable D0 and is relatively small, the small piece is restrained from being caught by the unevenness of the gap between the surface of the fuel cell 200 and the inner side surface of the fuel cell case 300.
- the gap between the small pieces can be made relatively small. Therefore, the small piece is densely filled in the gap between the surface of the fuel cell 200 and the inner surface of the fuel cell case 300.
- the Young's modulus as the intervening layer 121 can be increased.
- step S115 described above after forming the intervening layer 121 in the fuel cell case 300, as shown in FIG. 2, the filling of the small pieces is continued until the inside of the cylindrical portion 112a is filled with the small pieces.

- the restraining force F2 by the layer 121 becomes relatively large. For this reason, only the center part of the fuel cell 7e moves toward the center of the fuel cell 200 while the end of the end fuel cell 7e near the intervening layer 121 is restrained to the original position. As a result, as shown in FIG. 7, the end portion of the fuel cell 7e is bent, the seal by the seal portion provided in the vicinity of the end portion is broken, and the reaction gas or the cooling medium may leak. Therefore, in the first embodiment, the intervening layer 121 is formed so that the restraining force F2 is smaller than an allowable load (allowable stress) that does not cause seal breakage in the fuel cell 7e at the end.
- the allowable load is obtained by, for example, performing a bending test in which a load is applied along the stacking direction while supplying a test gas to the fuel cell 200 and specifying the maximum load that does not cause gas leakage. Can do.
- the binding force of the intervening layer 121 can be obtained by inserting the fuel cell 7 into the intervening layer 121, applying a load to the fuel cell 7 and specifying a load that moves by a predetermined distance within a predetermined period. .
- the adjustment of the restraining force F2 can be realized by adjusting the packing density of the small pieces.
- the restraining force F2 can be increased, and by reducing the filling density of the small pieces, the restraining force F2 can be reduced.
- Adjustment of the packing density of the small pieces can be realized by adjusting the average diameter of the small pieces. That is, the packing density can be increased by reducing the average diameter of the small pieces, and the packing density can be decreased by increasing the average diameter of the small pieces.
- the restraining force F2 of the intervening layer 121 is adjusted to be equal to or less than the allowable load, and the reaction gas or the cooling medium from the fuel cell 200 is adjusted. The occurrence of leakage is suppressed.
- the intervening layer 121 is formed between the fuel cell 200 and the fuel cell case 300, and the intervening layer 121 and the fuel cell case 300 satisfy the above formula (1). Therefore, even if the inertial force Fg assumed for the fuel cell 200 is applied and the inertial force Fg is applied to the intervening layer 121 and the fuel cell case 300, the deformation amount of the intervening layer 121 and the fuel cell case 300 is It is smaller than the variable X0. For this reason, even when the displacement of each fuel cell 7 constituting the fuel cell 200 occurs due to the deformation of the intervening layer 121 and the fuel cell case 300, the displacement can be made smaller than the allowable displacement X0. . Therefore, leakage of the reaction gas or the cooling medium from the fuel cell 200 can be suppressed.
- the intervening layer 121 satisfies the above formulas (2) and (3), the Young's modulus of the intervening layer 121 can be increased and the rigidity of the intervening layer 121 can be increased. For this reason, the spring constant K2 of the fuel cell case 300 is lowered while the spring constant (K1 + K2) of the composite layer (the layer between the intervening layer 121 and the fuel cell case 300) is kept the same, and the rigidity of the fuel cell case 300 is increased. Can be lowered. Therefore, a relatively light base material (for example, resin) can be used as the base material of the fuel cell case 300.
- a relatively light base material for example, resin
- the intervening layer 121 is formed of a small piece, the intervening layer 121 can be formed by supplying the small piece into the fuel cell case 300 after the fuel cell 200 is accommodated in the fuel cell case 300. .
- the small piece since a material having a diameter of 1/2 or less of the variable D0 is used as the small piece, the small piece is densely filled in the gap between the surface of the fuel cell 200 and the inner surface of the fuel cell case 300. can do. For this reason, since the Young's modulus of the intervening layer 121 can be increased and the spring constant K1 of the intervening layer 121 can be increased, the spring coefficient K2 of the fuel cell case 300 can be reduced. Therefore, the fuel cell case 300 can be formed of a lightweight material with low rigidity.

D>D0・・・(3)
図5は、第1実施形態における燃料電池装置100の製造方法の手順を示すフローチャートである。まず、燃料電池ケース300の部材、燃料電池200および小片体を用意する(ステップS105)。燃料電池ケース300の部材とは、端面カバー111と、上部カバー113と、底面カバー114とを意味する。ここで、第1実施形態の小片体の直径は、上述した変数D0の1/2以下である。次に、ケース部材を用いて、燃料電池200を収容するように燃料電池ケース300を組み立てる(ステップS110)。
図8は、第2実施形態の燃料電池装置の断面図である。図2に示す燃料電池装置100aは、燃料電池ケース300aの上部カバー113aが小片体供給部112を備えていない点と、介在層121に代えて、介在層121aを備えている点と、介在層121aが燃料電池200と底面カバー114との間にも形成されている点と、燃料電池装置の製造手順とにおいて、図2に示す第1実施形態の燃料電池装置100と異なり、他の構成は第1実施形態の燃料電池装置100と同じである。
