    • A cation-exchange membrane for electrolysis which comprises a fluoropolymer having ion-exchange groups and a porous base. It is characterized by having, on the anode-side surface of the membrane, protrusions comprising a polymer having ion-exchange groups. It is further characterized in that: when the average value of the heights of the tops of the protrusions from the anode-side surface of the membrane is expressed as h (μm), then 20≦h≦150; when the density of the protrusions distributed is expressed as P (protrusions per cm2), then 50≦P≦1,200; when the average proportion of the areas of those bottom parts of the protrusions which are on the same level as the anode-side surface of the membrane to the area of the anode-side surface of the membrane is expressed as S (cm2/cm2), then 0.001≦S≦0.6; and when the average proportion of the areas of the top parts of the protrusions to the area of the anode-side surface of the membrane is expressed as T (cm2/cm2), then T≦0.05.
    • 一种用于电解的阳离子交换膜,其包含具有离子交换基团的含氟聚合物和多孔基材。 其特征在于,在膜的阳极侧表面上具有包含具有离子交换基团的聚合物的突起。 进一步的特征在于:当膜的阳极侧表面的突起的顶部的高度的平均值表示为h(μm)时,则20≦̸ h≦̸ 150; 当分布的突起的密度表示为P(每cm 2的突起)时,则50≦̸ P≦̸ 1,200; 当与膜的阳极侧表面在膜的阳极侧表面的相同水平面上的突起的底部的面积的平均比例表示为S(cm 2 / cm 2)时, ,然后0.001≦̸ S≦̸ 0.6; 并且当突起顶部的面积与膜的阳极侧表面的面积的平均比例表示为T(cm2 / cm2)时,则T&NlE; 0.05。
