電性の点で問題があった。In order to reduce the number of constituent elements of the battery by integrating the bipolar electrode partition plate and the electrode and to reduce the weight of the battery, it is preferable to use the bipolar electrode partition plate (2). This bipolar electrode partition plate is shown in FIG. 5. The bipolar electrode partition plate 10 has a structure in which the conductive fibers 1 simply pass through the resin plate 2 in a dispersed manner and both ends of the fiber protrude outside the resin. Therefore, it is not possible to deal with the variation in the distribution of the current density on both sides of the electrode plate, and there is a problem in terms of conductivity.

電池反応が低下し、電圧効率が低下する。That is, in the battery reaction, the reaction on the electrode plate does not normally occur uniformly, but a difference in reactivity occurs, and therefore a difference in current density distribution also occurs. When an electrode plate having good conductivity is used, a current also flows in the vertical direction of the electrode plate, so that the current density distribution becomes uniform. However, in the bipolar plate as shown in FIG. Since it has almost no conductivity in the vertical direction, it cannot handle variations in current density, and as a result,
The battery reaction is reduced and the voltage efficiency is reduced.

集合体が樹脂板２を貫通する回数が多いほどよい。As the resin plate 2, a plastic sheet made of a thermosetting resin such as a phenol resin or an epoxy resin or a thermoplastic resin such as polyethylene or polypropylene is used. The thickness of the resin plate is usually about 0.1 to 5 mm. As the conductive fiber assembly 1, carbon fiber,
An aggregate (for example, carbon felt, carbon cloth, etc.) in which a plurality of conductive fibers such as various metal fibers are twisted together to form a twisted string and which is formed into a string, cloth or felt is preferably used. From the viewpoint of improving the electrical conductivity of the electrode, the longer the length of the strand used, the better, and the more the fiber assembly penetrates the resin plate 2, the better.

る。In the present invention, the length of one unit of the conductive fiber aggregate exposed on one side is within 20 mm, preferably within 15 mm. When the exposed length of one unit of the conductive fiber assembly exceeds 20 mm, the resistance inside the battery increases due to the voltage drop due to the electric resistance of the conductive fiber assembly itself. In the bipolar partition plate 10 according to the present invention, the conductive fibers 1 penetrating the resin plate 2 serving as a base material have good electrical conductivity in one-dimensional (line) and two-dimensional (surface) electrical contact with each other. Since it is possible to form a portion, it is possible to cope with variations in current density due to difference in reactivity in the electrode plate,
By setting the length of the conductive fiber exposed from the substrate to 20 mm or less, a battery having a low internal resistance can be constructed.
