Embodiment Construction
[0028] as attached figure 1 As shown, the bipolar plate 2 is folded in half at the lead wire, and a total of 11 pieces are folded; the U-shaped bipolar plate 2 is vertically placed inside the unipolar plate 1a, and the opposite polarity side is adjacent to the unipolar plate, and the bipolar plates are placed in sequence. A total of 11 bipolar plates 2 are stacked to ensure that the polarities are staggered, and a unipolar plate 1b with opposite polarity is placed outside the last bipolar plate; the separator is cut into a separator 3 that is 2.1 times the area of the side surface of the unipolar plate 1 , cutting a total of 24 pieces, and then folding them into a V shape to surround the aforementioned 24 polar plates respectively; cutting the insulating plastic film into 24 film sheets slightly larger than the area of the side surface of the unipolar plate 1, and pasting these films on the unipolar plate 1 respectively. The outer surface of the outer side of the polar pla...
