ABSTRACT:
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.
