摘要： A multi-bipolar electrode type of electrochemical cell which is adapted for operation with flowing electrolyte, comprises a plurality of bipolar electrode units, which can be, for example, rods, such as hollow rods, preferably horizontal, in vertical column, or groups of bipolar electrode units, which can be of geometrical shape, such as cylinders or rings, such as Lessing rings, arranged in horizontal layers one below the other separated by openwork, electrically insulating, spacers, such as nylon net. It is arranged that the electrolyte flows to bridge the spaces between adjacent electrode units, or groups of electrode units, but that any electrolyte in contact with the remainder of each electrode unit surface is kept to a very thin film. In this way electronic continuity through the cell is maintained by means of the electrolyte bridges and each electrode unit functions as a bipolar electrode.

摘要： 1,223,559. Gas-depolarized cells with fluidized bed anodes. NATIONAL RESEARCH DEVELOPMENT CORP. 13 March, 1968 [16 March, 1967], No. 12442/67. Heading HlB. The anodic half cell of a gas depolarized cell comprises a container having at least part of its walls permeable to electrolyte and containing anodic material at least partly consumable in particulate form, at least one electronically conducting member to provide electrical connection with the particles, and means to fluidize the particles. The particles preferably comprise a core, e.g. of glass or a plastics material, coated with anodically consumed material, and may be circulated for replacement or recharging outside the cell. Fig. 1 shows a halfcell comprising a container 1 in which one face 2 is a permeable or semipermeable membrane and a bed of zinc-coated glass spheres is fluidized by the electrolyte, which may be 5N aqueous KOH, which flows from inlet 3 via the porous distributer 7 to the outlet 4, electrical contact of the bed with terminal 6 being provided by a metal gauze 5 close to the diaphragm 2. Figs. 2 and 3 (not shown), show air depolarized batteries comprising such half-cells.

摘要： 1,194,181. Preparation of metanilic acid electrolytically. NATIONAL RESEARCH DEVELOPMENT CORP. 17 May, 1967 [24 May, 1966], No. 23070/66. Heading C2C. [Also in Divisions C7 and H1] An electrode for an electrochemical cell which may be used for cathodic reduction of mnitrobenzene sulphonic acid to metanilic acid comprises a bed of conducting and/or semiconducting particles and means whereby in operation the bed is fluidized, by upward passage therethrough of electrolyte, optionally containing one or more reactants. Fig. 1 shows a cell having a catholyte chamber formed by two flanged porous plastics tubes 1, 2 with a porous plastics plate 3 between them, above which lie the cathode particles, e.g. of copper powder, and round this an anolyte chamber formed by glass tube 5 lined with a lead anode 4, both chambers being closed by end plates 6, 7 through which pass catholyte and anolyte inlet and outlet tubes, a terminal 8 for the lead anode, a copper rod cathode conductor 9, and a reference electrode probe 14. In Fig. 2 (not shown), a single porous central tube houses the anode particles of, e.g. platinum, a surrounding glass tube contains the cathode particles of, e.g. copper, and both tubes have as base a single porous plastics plate, through which electrolyte is fed from a single chamber, cylindrical gauzes act as electrode conductors.
