泡性接着シートにて覆うようにした。Means for Solving the Problems In order to eliminate the above-mentioned drawbacks, the present invention interposes a metal having a lower electric resistance and a higher mechanical strength than a laminated structure graphite separator in the laminated structure graphite separator. The metal was extended to be an output terminal. Also,
Laminated structure Graphite separator is liquid impermeable in the direction of the lamination plane of the graphite sheet, but since the liquid penetrates from the plane orthogonal to the lamination plane direction, that is, the surroundings, it is recommended to use a highly corrosive electrolyte. However, for example, in a liquid fuel cell using sulfuric acid, usable metals are limited. Therefore, in order to protect the metal and the output terminal interposed in the separator from corrosion due to electric field, the present invention has a laminated structure. When the graphite separator and the output terminal are overheated, the volume of the graphite separator increases due to the expansion of the gas contained therein, and each of the output terminals is covered with a foaming adhesive sheet that serves as a porous elastic sheet composed of independent bubbles.
作用 出力端子の電気抵抗が小さくなるため、電圧の損失分が
小さくなり電池性能が向上する。出力端子の強度が高く

損を防止できる。Action Since the electrical resistance of the output terminal is reduced, the voltage loss is reduced and the battery performance is improved. Since the strength of the output terminal is increased, it is possible to prevent the output terminal from being damaged when the lead wire or the like is attached.
