Abstract: The filterpresstype electrolytic-cells of the present invention differentiate themselves from that presently available in the art by a modular structure and thus in that they are more simple and easy to be assembled. The mechanical elements (4) (5) (6) constituting the electrolytic cells (CE) are mechanically identical to constituting the condenser chambers (C) which are intended for condensating the steam present in the oxygen and the hydrogen there produced by electrolysis. The cooling, e.g. by air, of both the electrolytic cells (CE) and the condenser cells (C) is realised by using suitable passageways (5) provided within the electrodes elements (4) folded in U-form; said electrodes elements (4) ensuring a separating function and providing the cooling function in the condenser cells. The channels for the distribution of the electrolyte and for the withdrawal of the produced gases are formed by the compression to which are submitted cylindrical rings (6/1C, 6/2C) showing slits, provided in the structure of suitable spacing frames (6/1, 6/2) which allow the building up of the cells.

In these regions, as extensions of the intermediate layer, respective additional rubber strips are provided. Half of the width of a given rubber strip is disposed below the belt plies, and the other half of the width of that strip extends laterally beyond the belt. These rubber strips are harder than the low-damping intermediate layer.
