Mass transfer to the surface of a substantially horizontal, foraminous gas-evolving electrode, suspended in the electrolyte pool over a co-operating electrode, is improved by inducing a vigorous multiple recirculation motion of the electrolyte to and from the interelectrodic gap through the openings in the foraminous electrode exploiting the gas lift of evolved gas bubbles by means of a multiplicity of baffles, alternatively slanting one way and the opposite with respect to the vertical axis, and defining, with their lower edges, an alternating series of large and small areas over the foraminous electrode surface; electrodes and cells incorporating the hydrodynamic means to effect recirculation are also disclosed. |
