摘要： In a filter press-type electrolytic cell comprising a group of electrode plates arranged in parallel in face-to-face positions through insulators, a pair of metallic press heads for tightening the group of the electrode plates from both ends of the group, the press heads being provided at both ends of the group of the electrode plates, peripheral edges of the electrode plates being sealed by gaskets, supply and discharge of an electrolytic solution to and from spaces between the electrode plates being conducted through an inflow hole and an outflow hole bored on the individual electrode plates, an inlet and an outlet for the electrolytic solution are provided on only one of the press heads at both ends, the inlet is connected to a passage formed by the inflow holes of the individual electrode plates, the outlet is connected to a passage formed by the outflow holes of the individual electrode plates, an insulating plate of large thickness made from a non-electroconductive material is placed between the press head provided with the inlet and the outlet and the nearest electrode plate to the press head, and an inflow hole and an outflow hole are bored on the insulating plate and communicated with the inflow holes and the outflow holes of the individual electrode plates, respectively, thereby allowing the insulating plate to prevent the press head and the nearest electrode plate from direct facing. Galvanic corrosion of the press heads can be prevented.
