    • A microporous membrane roll (33) comprises cores (1, 11, 21, 31) formed in whole or in part from electrically conductive members (12, 13), and microporous membranes (34, S) which are wound around the cores (1, 11, 21, 31). A first surface (100) and a second surface (200) of the microporous membranes (34, S) are respectively equivalently charged with antipolar charges (102, 201). A method of manufacturing the microporous membrane roll (33) includes diselectrifying the microporous membranes (34, S) with a diselectrifier (35), and winding the microporous membranes (34, S) around the cores (1, 11, 21, 31) formed in whole or in part from the electrically conductive members (12, 13). When the microporous membranes (34, S) are unwound from the cores (1, 11, 21, 31), the microporous membranes (34, S) are prevented from being drawn toward either the microporous membrane roll (33) or peripheral devices by static electricity. The microporous membranes (34, S) are useful as a separator in either a fuel cell or a secondary battery.
    • 微孔膜卷(33)包括芯(1,11,21,31)中形成的全部或部分从导电构件(12,13)和其是芯缠绕的微孔膜(34,S)(1 ,11,21,31)。 的第一表面(100)和所述的微孔膜(34,S)的第二表面(200)分别等同地装入反极性的电荷(102,201)。 用diselectrifier(35)一种制造微孔膜卷(33)的步骤包括除电的微孔膜(34,S),和绕组的微孔膜的芯周围的方法(34,S)(1,11,21,31) 从导电构件(12,13)中全部或部分地形成。 当微孔膜(34,S)是从所述芯(1,11,21,31),所述微孔膜退绕(34,S)是从通过被被拉向要么微孔膜卷(33)或外围设备防治 静电。 微孔膜(34,S)是作为在任何一个燃料电池或二次电池的隔膜是有用的。
