Abstract: A single piece-type bipolar film roll with a mesh cloth support and a manufacturing method therefor. The single piece-type bipolar film roll is supported by a high-strength ultra-high molecular weight polyethylene mesh cloth, one side of the single piece-type bipolar film roll is a cation exchange layer containing a benzenesulfonic acid group, the other side of the single piece-type bipolar roll is an anion exchange layer containing a benzyl dimethyl butyl ammonium quaternary amino group, and the middle is a water dissociation catalyst layer containing a benzyl methyl butyl amine tertiary amino group, and the three layers form the single piece-type bipolar film roll.
