摘要： A membrane cell for the electrolysis of aqueous salt solutions is provided in which the foraminous metal anode is enclosed in the membrane. Spacing means are provided to separate the portions coated with an electrocatalytically active material from the membrane. The spacing means may be a nonconducting material or the coated surface of the anode may be faced away from the membrane to permit the anode structure to serve as the spacing means. To provide a low cell voltage and permit efficient hydrogen gas release from the caustic solution, the cathode is spaced apart from the membrane.

摘要： Electrolysis of alkali metal chloride solutions to produce chlorine and alkali metal hydroxides is accomplished in a cell comprising an anode compartment, a cathode compartment, a cation permeable divider separating the anode compartment from the cathode compartment, where the anode compartment contains an anode separator. The anode separator is comprised of a porous plate of a valve metal having an electrochemically active coating on the face, and an electrochemically non-active barrier layer on the back and a portion of the interior. The anode separator is positioned in the anode compartment so that the back of the anode separator is spaced apart from the cation permeable divider. An alkaline brine zone is formed between the anode separator and the cation permeable divider which increases the service life of the cation permeable divider. In addition, the anode separator provides improved chlorine gas separation properties, increased service life for the electroconductive coating on the face, and enables the cell to operate with a reduced cell voltage.

摘要： An electrolytic cell suitable for use in electrolyzing ionizable chemical compounds, particularly alkali metal halide brines and hydrohalic acids, which comprises a cell body having an anode compartment containing a porous anode and a cathode compartment containing a cathode said compartments being separated from each other by a prestretched, taut membrane barrier which is substantially impervious to gases and liquids and which is selected from a hydrolyzed copolymer of a perfluorinated hydrocarbon and a sulfonated perfluorinated hydrocarbon and a sulfonated perfluorovinyl ether, and a sulfostyrenated perfluorinated ethylene propylene polymer, said barrier being pretreated by hydrolyzing and stretching prior to insertion in the cell.Such cells can be operated at constant low voltage, and are not subject to erratic operating voltages which are due, in part at least, to the accumulation of gases between the anode and diaphragm.
