本発明は、積層型燃料電池の収納装置に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a storage device for stacked fuel cells.
燃料電池の積層は電池枠、陽極、電解質板、陰極そして
電池枠の順に順次に積み重ねることによって多数のセル
が積層される。積層されたセルはセル端に絶縁物を介し
、その外側に端板を配設し、この端板間にポルＩｆ通し

冷熱サイクルにより伸縮が起こるため、ばね、スプリン
グワッシャ等を用いて伸縮を吸収する方法が考えられる
。In stacking a fuel cell, a large number of cells are stacked by sequentially stacking a battery frame, an anode, an electrolyte plate, a cathode, and a battery frame in this order. In the stacked cells, an insulating material is interposed between the cell ends, an end plate is disposed on the outside thereof, and a pole If is passed between the end plates and tightened with a nut. Since stacked batteries expand and contract due to thermal cycles, a method of absorbing expansion and contraction using springs, spring washers, etc. is considered.
しかし、リン酸型燃料電池は約２００Ｃ溶融炭酸塙燃料
電池は約６５００で運転されるので、前述のばね、スプ
リングワンシャ等は劣化されてしまう。However, since the phosphoric acid fuel cell is operated at about 200C, and the molten carbonate bunker fuel cell is operated at about 6500C, the springs, spring springs, etc. described above are deteriorated.
本発明の目的は、積層型燃料電池が冷熱サイクル時に生
じる膨張、または収縮に対しても、締付けが一定荷重下
に保持され、かつ電池は気密保持された雰囲気下に置か
れ、安全に運転できるような構造金有する電池の収納装
置を提供することにある。The purpose of the present invention is to maintain the fastening under a constant load even when the stacked fuel cell expands or contracts during the cooling/heating cycle, and the battery is placed in an airtight atmosphere so that it can be operated safely. It is an object of the present invention to provide a battery storage device having such a structure.
本発明は積層電池をボルトで締め付けただけの組立てで

圧可能な昇降機全連動させて自動的に調圧可能にした点
に特長がある。The present invention focuses on the fact that if a laminated battery is assembled by simply tightening bolts, the bolts will loosen due to expansion and contraction during heating and cooling, and the tightening effect will be lost. The feature is that the load sensor and all the elevators that can adjust the pressure are linked to automatically adjust the pressure so that it can be removed.

ところに第２の特長がある。Large stacked solvent batteries, which are made up of a large number of stacked cells, are designed as safety measures in the event that the reactant gas introduced to cause the battery reaction leaks between the cells or from piping or vertical lines. The entire battery must be covered and kept airtight. In order to prevent the introduced reactive gases, ie, H2 on the anode side and 02 on the cathode side, from causing contact reactions due to leakage other than cell reactions, an inert gas must always be introduced and filled into the cover. The second feature of the present invention is that it uses a stretchable and heat-resistant bellows as a method for maintaining airtightness.
以下、本発明の実施例を図面により説明する。 Embodiments of the present invention will be described below with reference to the drawings.

は上下に移動する機能を有しておム燃料電池１゛を取り
はずす時はシリンダ１０’ａ−降ろせばよい。The figure shows a storage device for a molten carbonate fuel cell made by implementing the present invention. - The fuel cell 1 is sandwiched between upper and lower end plates 2, and ceramic insulators 3 are placed on the outside of the upper and lower end plates 2, respectively. The fuel cell l is held between a holding plate 6 and a holding table 7 attached to a support 5 fixed to a base 4 and extending upward, and a load sensor 8 is attached to the fuel cell l.
and the cylinder ll of the elevator 10 via the sensor piece 9
' is pushed up and pressurized by the signal from the pressure regulator 12, and a load is applied to the fuel cell 1 and tightened. Of course, cylinder 10 of elevator 9
The cylinder 10'a has the function of moving up and down, and when the fuel cell 1' is removed, it is sufficient to lower the cylinder 10'a.
燃料電池ｌの組立、締付けが終了した後、ベルジャー１
２をかぶせる。After assembling and tightening the fuel cell 1, attach the bell jar 1.

の下部とベース４との間をベローズ１７で連結した。As a safety measure in case the reactive gas introduced into the battery leaks from between the stacked cells, an inert gas Ntk purge gas inlet 14 flows into the bell jar 13, saturates the inside of the bell jar 13, and drains the purge gas. It flows out from the outlet 15. For this reason, the inside of the bell jar 12 must be kept airtight. The bell jar 12 and the base 4 are kept airtight with a backing 16, and the base 4 and the holding stand 6 are held together by the holding stand 6.
A bellows 17 connects the lower part of the base 4 with the base 4.

During the electrolysis process, a load was gradually applied to the fuel cell l using the elevator 10 from 500U, where the carbonate in the electrolytic salt began to dissolve, to 2Kg/cvl at 650C.

によって差がある。If the pressure of the elevator is set as is while the fuel cell 1 is in operation, the fuel cell 1 will expand and after the io waiting time the pressure will be 2.67.
Kg/an increased by 21. In addition, I went into labor with the unloader's pressure at full pressure (and as a result of cooling it to room temperature, it turned out to be 0.
The load decreased to 8Kg/Cm2. - The expansion and contraction of the fuel cell 1 varies depending on the number of stacked cells, the material and composition of the electric MiK plate, etc.

明はこれらの要因を排除し、安全な運転が可能となる。According to the present invention, when tightening the fuel cell, the load can be automatically adjusted, so that no unreasonable load is applied and no distortion is caused to the fuel cell. The electrolyte plate is made of ceramics, so the heavy load is the biggest cause of cracking, leading to a gas short circuit between the anode and cathode, making it impossible to obtain normal battery output, or even causing an explosion. It is extremely dangerous. The present invention eliminates these factors and enables safe driving.

It can be said that it is a device with excellent airtightness, high safety, and mass production is easy.
