As shown in the figure, a conductive metal plate 1 having the same shape as the outer end surface of the interconnector plate 10 located outside of the fuel cell 1 of the stacked body 2 is placed on the outer end surface. While fixing with adhesive, an L-shaped highly conductive metal plate 12 is joined to the center of the outer surface of the metal plate 11 by welding or silver brazing, and a current is passed through the metal plate 12 to the external current path 3.

１１を平面研磨するか、あるいは凹凸を吸収するために
多量の導電性接着剤を用いるか、何れかが必要となる。For this reason, it is desirable to have a function to sufficiently even out the zero current distribution within the bald plate, and to have a sufficient allowable current capacity. Therefore, in the conventional device, the metal plate 11 is fixed to the end face of the laminate 2 with a conductive adhesive so as to cover the entire end face to make the current distribution uniform. The L-shaped metal plate 12 is attached to the outer surface by welding or silver brazing to construct a current path with sufficient allowable current capacity. The metal plate 12 needs to have a large wall thickness in order to ensure a sufficient allowable current capacity, and the contact area of the metal plate 12 with the metal plate 11 needs to be widened in order not to adversely affect the uniformity of the current distribution. In this way, when the thick metal plate 12 is welded to the metal plate 11 with a sufficiently wide welding area, if the thickness of the metal plate 11 is thin, the metal plate 11 is likely to be thermally deformed during welding. When the metal plate 11 is thermally deformed, 'this metal plate 11
In order to adhesively fix the metal plate 11 to the interconnector board 10, it is necessary to either flatten the metal plate 11 or use a large amount of conductive adhesive to absorb the unevenness.

かつ大重量化する欠点があった。However, surface polishing is not preferable because it increases the number of steps, and using a large amount of conductive adhesive is also not preferable because it increases the electrical resistance in the adhesive layer. For this reason, in the conventional device, a sufficiently thick metal plate 11 is used to prevent thermal deformation during welding, which not only increases material costs but also increases the overall size and It had the disadvantage of being heavy.
本発明は、このような事情に鑑みてなされたもので、そ

An object of the present invention is to provide a fuel cell device that is lightweight and has a high output.

達成したものである。That is, the present invention provides a current extraction terminal with a first flat plate portion having an area that can cover half of the end face of the laminate and the first flat plate portion.
Each of the flat plate parts has a second flat plate part bent with respect to the first flat plate part, and the second flat plate parts are placed back to back in close contact with each other. The above object was achieved by forming a metal plate and fixing the flat plate part of the container 16- of the current extraction terminal between the ends of the layered body with adhesive so as to cover the entire end surface. It is something.

The second flat plate parts 24 are brought into close contact with each other back to back, and in this state, each first flat plate part 23 is adhesively fixed to the end face with a conductive adhesive so as to cover the entire end face of the laminate 2. Each second flat plate portion 24 in close contact is used as an external connection portion 25. Note that the width of the second flat plate portion 24 indicated by W in FIG. 4 is set to a dimension that allows the cross-sectional area of the external connection portion 25 to be approximately equal to that of the external current path.
