Abstract

1387930 Electric cell VARTA AG 9 June 1972 [11 June 1971] 27105/72 Heading HIB An electrochemical cell comprises an electrode having a rechargeable active mast of one polarity, a gas electrode of the other polarity and an intermediate porous diaphragm, the gas electrode comprising an open system of fine pores and an open system of coarse pores connected to a gas conduit at one or more points on the periphery of the gas electrode. The capillary pressure of the diaphragm pores is greater than that of the gas electrode pores. The electrode of one polarity may be nickel impregnated with cadmium hydroxide, alternatively the cadmium may be replaced by Co, Fe, Zn or Cu. The gas electrode is an oxygen or air electrode of nickel carrying grannular Raney (RTM) Ni or Ag, Pt, Ag, activated C or a spinel. Alternatively, a hydrogen diffusion electrode with a PbO2 electrode using an acid or alkali electrolyte may be used. The electrolyte is preferably KOH while the diaphragm is of asbestos board optionally supported by at least one gauze sheet or a fine-meshed sheet on either side and a coarse-meshed sheet in the middle. In operation the electrodes are conected in parallel during discharge but during recharge the oxygen electrodes are disconnected. The electrolyte may be pulsed through the cells at different pressure and a heat exchange system used or the electrolyte streams. If any cell is overcharged then the hydrogen evolved is collected and fed to a hydrogen electrode in the cell. The build up of gas in the cells may be used to push electrolyte through the cells. If the oxygen is supplied by the air then an inert gas cascade is used to remove the nitrogen.
