を貫通して導出された外部端子である。 As is well known, the battery stack 1 includes a unit cell S consisting of an air electrode 2, a hydrogen electrode 3, and an electrolyte matrix 4 interposed therebetween, and passages 6 and 7 for each reactive gas (air and hydrogen) formed on both sides. A large number of carbonaceous gas separation plates 8 are stacked alternately (see Fig. 3 for the above) and fixed by tightening between upper and lower contact plates 9 through terminal plates and heat-resistant insulating plates (none of which are shown). be done. In the figure, 10 is an insulating plate and a contact plate 9 from the terminal board.
This is an external terminal led out through the.

た。 Conventionally, a frame-shaped sealing member 13 made of fluorine rubber is interposed between the sealing part between the stack 1 and each manifold 11, 12, and the upper and lower mounting collars of each manifold are connected to the upper and lower abutting plates 9, 12 of the stack 1 by bolts 14.
It was fixed at 9. However, the seal in the stacking direction of the stack 1 is only pressed by the mounting collar of the manifold through the seal member 13, and even when the bolts are tightened, the packing effect is not sufficient to prevent gas leakage. Moreover, there was a problem in that the sealing member in this part was deformed or shifted and blocked the gas passage 6 or 7 of the gas separation plate 8.
本考案は、このような問題を解消するもので、
その特徴とする所は、スタツク積重方向シール面
に凹溝を形成し、ここの凹溝にシール部材の突条
を嵌合してマニホルドを締付固定する点にある。 This invention solves these problems,
The feature is that a concave groove is formed on the sealing surface in the stacking direction, and the protrusion of the seal member is fitted into the concave groove to tighten and fix the manifold.
以下本発明の実施例を図について説明するが、
該当部分は前記図面と同一記号を付した。 Examples of the present invention will be described below with reference to the drawings.
The corresponding parts are given the same symbols as in the above drawing.

重面に、凹溝１７を構成する。 As seen in FIG. 3, each corner portion (sealing portion) of the stack of unit cells 5 and gas separation plates 8
In this case, only the matrix 4 is interposed between adjacent gas separation plates. Therefore, before assembling the stack, grooves 15 and 16 are formed in advance on both sides of each gas separation plate 8 and matrix 4, and then these grooves 15 and 16 are formed.
It is assembled into a stack, and a groove 17 is formed on the stacking surface of the stack so that the stacking surfaces coincide with each other.

いる。 The frame-shaped seal member 18 made of fluorine rubber is
As shown in FIGS. 4 to 6, a protrusion 18' is formed only in the stacking direction, and its cross section is L-shaped.

により締付けられる。 When each manifold 11, 12 is attached to the stack 1, the protrusion 18' of the seal member 18 is engaged with the groove 17 on the stack stacking surface, and the seal member 18 is
Bolts 14 pass through the upper and lower mounting collars of each manifold 11 and 12 and the upper and lower sides of the sealing member 18 and are screwed into the upper and lower end plates 9 of the stack 1, as in the conventional case.

ル面のようなシール構成を必要としない。 Note that the upper and lower sides of the frame-shaped sealing member 18 are bolted with the stack end plate 9 as the sealing surface as described above, so there is no risk of the sealing member in this part shifting. It is separated from the main body by an insulating plate and terminal board, so
Even if the sealing member is deformed during tightening, there is no risk of blocking the reaction gas passages 6 and 7, so there is no need for a sealing structure such as a sealing surface in the stacking direction.

利点がある。 The protrusion 18' of the sealing member 18 may be integrally provided from the sealing surface thereof, but if it is provided protruding from the inner edge of the frame-shaped sealing member as in the above embodiment, it can be tightened (L-shaped in cross section). Even if a force is applied, there is an advantage that elongation or deformation in the direction of the reaction gas passage can be almost completely prevented.
