。Conventionally, as a countermeasure against this, for example,
As shown in the above publication, it is known to provide a support between the tJL battery body and the storage tank to prevent vibration of the battery body. However, although this can reduce the force applied to the stacked battery when a horizontal load is applied, it increases the force applied to the support and storage tank that prevents photography, reducing the strength of the support and storage tank. It was necessary to increase. Furthermore, the structure for connecting the support and the storage tank becomes complicated, resulting in an increase in the number of man-hours required for assembling the fuel cell.
本発明は以上の点に鑑みなされたものであり。 The present invention has been made in view of the above points.

A battery body having a battery and a manifold is attached to a fuel cell fixed to a base, and a spring mechanism is provided between the battery body and the base to absorb energy by friction when the battery body is compressed. This makes it possible to provide a spring mechanism between the battery body and the base that absorbs energy through friction when it is compressed.

Note that parts that are the same as those in the conventional system are given the same reference numerals, and therefore their explanations will be omitted. In this embodiment, a spring mechanism 9 is provided between the battery body 6 and the base 7, which absorbs energy by friction when the spring mechanism is compressed. By doing this, a spring mechanism 9 is provided between the battery body 6 and the base 7 that absorbs energy through friction when the spring mechanism is compressed, thereby improving vibration resistance. It is possible to obtain a fuel cell that makes it possible to

．． #i Bolt 12 that passed through the impact material 10 and the lower fastening fitting 2. Installed with nut 13. And this bolt 12
The spring mechanism 9 held by the nut 13 so as to maintain a predetermined tightening force is composed of a plurality of disc springs stacked one on top of the other so as to absorb vibration energy through friction when compressed.

上できる。By doing this, if the tightening force of the spring mechanism 9 is set to a value that has sufficient margin against the horizontal load that would cause the mutual displacement of the stacked batteries 4 or the cracking of the stacking member, the spring mechanism 9 The moment the amplitude reaches a bending load that exceeds the set pressure, compression of the spring mechanism 9 begins, and when it attempts to swing with an even larger amplitude, the energy is absorbed by the friction of the spring mechanism 9, damping the bulge. As a result, safety against vibrations of the battery body 6 is maintained. In this way, the acceleration response of the battery body 6 is not much larger than when the spring mechanism 9 starts to be compressed, and the battery body 6 is more easily resistant to large earthquakes than when the battery body 6 is firmly fixed to the base 7 without the spring mechanism 9. safety can be ensured. That is, even if a large vibration is applied to the base 7, the energy is absorbed by the spring mechanism 9, thereby improving the safety of the battery body 6 against vibrations and improving the earthquake resistance of the fuel cell.
