ABSTRACT:
A membrane electrolysis cell, particularly suited for producing chlorine, caustic soda and hydrogen by the electrolysis of brine, has its cathode formed by a static bed of a packing material capable of withstanding the cathodic conditions confined between the membrane and a current distribution-baffle plate, parallel and spaced from the membrane. The current distribution plate defines a space within the cathodic compartment through which de-gassed catholyte downflows toward the bottom of the compartment for raising again through the interstices of the cathodic static bed. The internal recycling motion permits a rapid evacuation the gas evolved at the cathode from the interstices of the cathodic bed and prevents catholyte stagnation within the cathodic bed.
