していた。BACKGROUND OF THE INVENTION Conventionally, this type of fuel cell requires close contact between electrodes and electrolyte in order to obtain stable cell performance. Also,
It is necessary to pressurize the gasket that seals the liquid inside the battery. These two types of surfaces were simultaneously pressurized by placing pressure plates with bolt holes at both ends of the battery body and tightening these pressure plates and the battery body with bolts and nuts.

問題があった。Problems to be Solved by the Invention The conventional fuel cell described above is shown in FIG. The battery body is tightened and pressurized using the pressure plate 7, bolts 8, and nuts 9. Liquid sealing is performed by pressing the gasket 3 into close contact with the separator 1 and the battery frame 2. Moreover, the electrode 4.5 and the electrolyte 6 are brought into close contact by pressurizing the electrode 4.5 with the separator 1. In this way, the ζ electrode surface and the sealing surface are pressurized at the same time, and conventionally, in order to optimize the pressurization on both sides, the tightening of the battery body was limited to the later dimensions.
The pressure applied to the electrode surface and sealing surface at that time was measured in advance, and the pressure was applied accordingly. If this method uses an electrode that is thicker than the designed value and pressurizes the electrode and electrolyte to achieve optimal adhesion, the sealing surface will not be pressurized enough, causing liquid leakage. If the pressure on the sealing surface was optimized in this state, there was a problem that the electrode would be damaged.

２０■以内にしなければならないという欠点があった。Furthermore, if an electrode is used that is thinner than the designed value and the adhesion between the electrode and the electrolyte is optimized, the pressure on the sealing surface will be excessive, causing wrinkles in the gasket and causing liquid leakage. On the other hand, if the pressure applied to the sealing surface is optimized, the adhesion between the electrode and the electrolyte decreases, causing the problem that stable battery performance cannot be obtained. Similarly, the above-mentioned problems occur when the thicknesses of other battery components change. In order to pressurize the electrode surface and the seal surface simultaneously to the optimum state, the dimensional accuracy in the thickness direction of the battery components should be reduced by 1/2.
There was a drawback that it had to be within 20 ■.
本発明は上記欠点を解決することを目的とするものであ
