PROBLEM TO BE SOLVED: To solve a problem of a bipolar electrode plate of a conventional water electrolytic cell that the working cost is expensive, and not economical, and the ratio of the weight of the bipolar electric plate to that of the cell is pretty large in the O-ring type, or that the cell voltage between each cell is largely different, the maintenance control is difficult, the sealability is inferior to that of O-ring type, and the operation of around 5 kg/cm<2> G is critical in the gasket type. SOLUTION: A plastic plate 2 having a power supply body storage hole 9 is arranged on each side of a metallic plate 1, a seal part 6a is provided on a peripheral edge part or on the inner side of the peripheral edge of the plastic plate, one or more water introduction hole 7 into an anode, an oxygen discharge hole 4, and a hydrogen discharge hole 5 are provided on the outer peripheral of the power supply body storage hole 5, a bipolar electrode plate in which the outer periphery of the water introduction hole into the anode and the oxygen discharge hole is sealed in one plastic plate, while the outer periphery of the hydrogen discharge hole is sealed in the other plastic plate is used. |
