Abstract

Simple, economic electrolysis appts in which the electrolyte flow accelerates diffusion at all electrode surfaces for a single expenditure of kinetic energy, with insertions on the two end faces to ensure a uniform velocity distribution across whole width of cell of the electrolyte flowing parallel to the electrode surfaces, has several cells connected consecutively in a common bath without dividing walls. All electrode surfaces are parallel and the distance between 2 consecutive electrodes in 2 different cells is at least 4 times that between 2 electrodes in same cell. Linear distance between 2 consecutive cells can be reduced by inserting deflection plates made of non-conducting material. Flow promoting diaphragms used to separate anode and cathode space.
