A filter-press type electrolyzer equipped with electrodes consisting of solid metal plates (2), called "plate electrodes", and of latticed or perforated plates (5, 6), called "pre-electrodes", parallel to the plate electrodes and separated from the latter by bracing tongues (7), the pre-electrodes enclosing a diaphragm (4) for each cell. The pre-electrodes are equipped with solid strips (61, 62, 63), which are all parallel to one another and parallel to the welding direction; each bracing tongue (72) has the shape of an S and is welded to the associated pre-electrode on a solid strip (62) of the latter and to the associated plate electrode, so as to leave a slight gap (J) from the tongue (71), located in quasi-continuous manner on the opposite face of said plate electrode, and the bracing tongues are placed in a staggered arrangement, as viewed in a plane parallel to the electrodes.
