As shown in Japanese Patent No. 5774, the main battery constituent members, such as electrolyte plates, electrodes, separators, etc., are made into flat plate shapes, and a large number of these plates are layered f1 to form a battery structure.

えられている。In addition, it is generally known that in order to maintain battery performance at a high level during operation, the above-mentioned structural members are pressurized from above or below to maintain a constant surface pressure at the interface of each member. ing. Various methods have been devised for pressurizing the battery, and broadly speaking, there are methods for pressurizing the battery. A method of tightening the battery using a tightening rod, and Japanese Patent Application Laid-Open Nos. 58-53166 and 1987-119
As seen in Japanese Patent Laid-open No. 170 and Japanese Patent Laid-Open No. 59-138057, there is a method in which a pressure unit using a certain type of pressure fluid is disposed above or below the battery stack to tighten the battery stack. In the former method, in molten carbonate fuel cells that are normally operated at temperatures as high as 650°C, high-temperature creep elongation of the clamping rods occurs, and the clamping surface pressure of the battery decreases over time, resulting in a decrease in battery performance. There are drawbacks that can have negative effects. on the other hand,
The latter method can solve this problem, but when the battery is tightened, a reaction force equal to the battery tightening force is always generated. You will be working on a flat floor surface. For example, the size of the battery is 150X150a+? The minimum battery tightening surface pressure should be 2 kg/a+? Even if this is assumed, the reaction force exerted on the floor surface generated by the pressure unit will be 45 tons. Therefore, if a power generation plant of around 100 MW class is assumed, the battery installation location would be located on the mezzanine floor of the building.
The lower floor will have a structure where auxiliary equipment supplies, piping, etc. will be installed.
この場合、電池の１モジユールを５００Ｗとすると２０
０個の電池が必要となり、電池締付による床面に働く反
力は実に９０００トンにもなる。In this case, if one battery module is 500W, then 20
Zero batteries are required, and the reaction force acting on the floor due to battery tightening is actually 9,000 tons.

の無い好適な電池締付構造を提供することにある。However, with conventional fuel cells, it has not been solved how to deal with the enormous cell tightening surface pressure mentioned above, so in order to put it into practical use, the floor strength of the building must be extremely strong, making it difficult to install. many issues remain. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a suitable battery clamping structure in which the reaction force of the battery clamping surface pressure does not affect the battery installation floor surface in any way.

り解決した。To achieve the above object, the present invention provides a fuel cell structure in which a battery stack and a base plate are attached to a battery clamping rod independent from the floor surface, a pressure unit is attached to the base plate, and the battery stack is tightened to the pressure unit. This problem was solved by constructing a structure in which the entire battery is placed on the floor through a battery storage container, and the battery clamping force by the pressure unit is applied to the battery stack and the base plate by pushing against each other via a clamping rod.

However, since both are self-balancing with the tightening rod, there is no shadow on the floor! I won't give you anything.

による効果と全く同一の効果が得られる。An embodiment of the present invention will be described below with reference to FIG. The battery stack 1 is sandwiched between upper and lower insulating plates 2 made of ceramic or the like that electrically isolate the battery stack 1, and is installed between an upper clamping plate 4 and a lower clamping plate 5. A tightening rod 3 is attached to the upper tightening plate 4 with a tightening nut 4a. On the other hand, a base plate 6 is attached to the other end of the tightening rod 3 with a tightening nut 6a. In addition, a play hole 5a is bored in the lower tightening plate 5, and a tightening rod 3 is inserted into the play hole 5a.The lower tightening plate 5 is rotated vertically with the tightening rod 3 as the axis It has a structure that allows it to slide freely. A pressure unit 7 for applying a tightening surface pressure to the battery stack 1 is installed on the base plate 6.
Between the cylinder rod 7a and the clamping shaft 9 for pushing up the lower clamping plate 5 and applying surface pressure to the battery stack 1, there is a load cell for detecting the clamping force and adjusting the optimum clamping force. The structure includes a detector 8 such as the following. According to this structure,
The clamping force applied to the battery stack 1 by the pressure unit 7 is transmitted to the upper clamping plate 4, while the reaction force of the clamping force is transmitted to the base plate 6. Further, the upper clamping plate 4 and the base plate 6 are fixed to the clamping rod 3 by clamping nuts 4a and 6a. Therefore, the reaction force of the clamping force 2 acting on the upper clamping plate 4 and the base plate 6 acts to pull the clamping rod 3 together, and therefore, the clamping force applied to apply surface pressure to the battery stack 1 causes It is a self-balancing structure that does not apply unnecessary force to the fixing part between the storage container legs 11 and the floor surface 12 or to the floor surface 12. By using this structure for batteries, the strength of the floor of the battery installation building only needs to be long enough to withstand the weight of the batteries themselves, making the entire building lighter and more compact, as well as reducing construction costs. In addition, as a modification of the present invention, as shown in FIG. 2, the tightening rod is divided into two in the longitudinal direction, and the tightening of each of the divided sections is performed within a range that does not cause any problem in terms of the strength of the tightening rod or the battery storage container. Even with a structure in which the center of the rod is shifted, the same effect as that of the present invention can be obtained.

れる。According to the present invention, since it is a self-balancing type that balances the reaction force when tightening the battery with the tightening force, it is possible to reduce the load on the floor surface of the battery installation location, and it is possible to reduce the weight of the battery storage building.
