    摘要： A structure of cathodic fingers for a chlor-alkali diaphragm cell with improved voltage and faradic efficiency is described, characterized in that a sheet provided with projections is inserted inside each finger. The interwoven wire mesh or 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.
