Abstract

A process for joining fluorinated polymer cation exchange membrane is provided, wherein fluorinated polymer cation exchange membranes containing the pendent groups of -COOH on at least one side of the membranes are treated with a tertiary amine or a quarternary ammonium base, then heat- pressed.
