摘要：A bipolar diaphragm or membrane electrolyzer comprising a housing containingan end anode element, an end cathode element and a plurality of bipolar elements withtheir major dimensions lying in a substantially vertical plane and comprised of a bipolarwall (1) separating the anode compartment and the cathode compartment and verticalforaminous electrodes (4) (6) parallel positioned a certain distance from the bipolar wall,diaphragms or membranes (7) separating the anodes and cathodes, a series of baffles (3)(5) distributed along the entire width of the electrode compartment and extending fromthe bipolar wall to the foraminous electrode to form a series of vertical flow channelsextending over a large portion of the height of the wall, the said baffles being alternatelyinclined one way (3a) and the other way (3b) with respect to the vertical plane normal tothe bipolar wall plane and spaced from one another whereby the ratio of the electrodesurface intercepted by the edges of two baffles laterally defining a vertical flow channel(C) to the flow section thereof is different from the ratio of the electrode surfaceintercepted by the edge of one of said two baffles and the edge of the adjacent baffle in
the series and the flow section of the adjacent channel (D) in the series to the said verticalflow channel, novel bipolar elements and improved methods of electrolysis
