ABSTRACT:
Disclosed is a method of preparing a cathode-diaphragm assembly for an electrolytic cell, where the diaphragm is adherent, e.g., to itself and to the cathode. The cathode-diaphragm unit is prepared by first depositing a protective film on the catalytic cathode, and thereafter depositing the diaphragm material under such conditions that the diaphragm material becomes self-adhereing and conforms to the cathode but is spaced from the cathode. In this way the diaphragm is subsequently removable without damage to the cathode catalyst.
