Method of installation of membrane to electrolytic cell

摘要

A cation exchange membrane is installed to an electrolytic cell to be used in a form of a cation exchange membrane of a fluorinated polymer having ion exchange groups having the formula -(COO)mX wherein X represents an alkali metal atom or -NRR' and R and R' respectively represent hydrogen atom or a lower alkyl group; and m represents a valence of m, by covering a membrane of a fluorinated polymer having ion exchange groups having the formula -COOL wherein L represents hydrogen atom or a C1-C20 alkyl group on said electrode in the installation.
