    • A structure of cathodic fingers for a chlor-alkali diaphragm cell with improved voltage and faradic efficiency is described, characterised in that a sheet provided with projections is inserted inside each finger. The interwoven wire mesh of the perforated sheet, forming each finger, is secured by a conductive connection, preferably by welding, to the top of each projection, thereby providing optimal uniformity of the electrical current distribution. The projections have a shape preferably equivalent to spherical caps, disposed in a quincuncial pattern. The internal volume of each finger is subdivided by the sheet provided with projections into two portions wherein both the free upward motion of hydrogen bubbles and the free longitudinal motion of the separated hydrogen take place towards the cell perimetrical chamber. Within the internal volume of each finger, which is only partially occupied by the projections, the natural recirculation of the solution constituted by the product caustic soda and the depleted sodium chloride also occurs, supported by the hydrogen bubbles.
    • 描述了具有改进的电压和法拉第效率的用于氯碱隔膜电池的阴极指的结构,其特征在于,在每个指状物内插入设置有突起的片。 形成每个手指的多孔板的交织丝网通过导电连接(优选通过焊接)固定到每个突起的顶部,从而提供电流分布的最佳均匀性。 突起具有优选地相当于球形帽的形状,以金属图案设置。 每个手指的内部体积被设置有突起的片材细分成两部分,其中氢气泡的自由向上运动和分离的氢气的自由纵向运动朝向细胞周边室发生。 在每个手指的内部体积中,其仅部分地被突出部分占据,由氢气泡支撑,由产物苛性钠和贫化的氯化钠构成的溶液的自然再循环也发生。
