Abstract

PURPOSE: To lower electrolytic voltage by bringing a hydrophilic porous thin film forming body having prescribed thickness and porosities into pressure contact with at least one of membrane surfaces.
CONSTITUTION: A porous thin film forming body of 10W99% porosities and 0.1W 1,000μm thicknesses, such as carbon fiber assemblage, made of hydrophilic material or applied with a hydrophilic treatment is brought into pressure contact with at least one of the surfaces of a membrane. Said membrane is a fluorine cation exchange membrane containing a sulfonic acid group, a carboxylic acid group or a phosphoric acid group. This ion exchange membrane for electrolysis made in this way is suited for electrolysis of water, acids or aq. alkali solns. and lowers electrolytic voltage.
