ABSTRACT OF THE DISCLOSURE An improved anode structure for a chlor-alkali type diaphragm cell wherein the anode is A porous, valve metal, e.g., titanium, anode having on one side a coating of a noble metal or noble metal oxide and on the uncoated side a memorane com- posed essentially of a cation-active permselective material which is substantially impervious to liquids and gases. The membrane covered surfaced is disposed spaced from but facing the cathode member. Anodes of this improved structure give minimum cell voltage and a surprisingly reduced consumption rate of the noble metal or oxide coating. - 1 -
