Abstract

A method for joining fluorinated polymer cation exchange membranes is provided, wherein fluorinated polymer cation exchange membranes containing pendent groups of sulfonic acid groups or sulfon amide groups are treated with a tertiary amine, a quarternary ammonium base, or a salt thereof, then a porous hydrophilic fluorinated polymer film is interposed between them, thereafter being heat-pressed. The invention provides more improved joining than conventional methods.
