Claims (1)

Изобретение относится к электролизатору, содержащему по меньшей мере одну элементарную ячейку с новым деполяризующим водород анодным узлом, и к соответствующему способу получения родственных основания и кислоты соли посредством электролиза растворов, содержащих указанную соль. Указанный деполяризующий водород анодный узел содержит катион-обменную мембрану, электрокаталитический лист и жесткий коллектор тока, который создает на указанном электрокаталитическом листе множество контактных точек, причем указанные мембрана, электрокаталитический лист и коллектор тока отличаются тем, что они прижимаются друг к другу давлением, создаваемым электролитом и/или упругим средством электролизатора.The invention relates to an electrolytic cell containing at least one unit cell with a new hydrogen depolarizing anode site, and to a corresponding method for producing related bases and acid salts by electrolysis of solutions containing said salt. The hydrogen depolarizing anode site contains a cation-exchange membrane, an electrocatalytic sheet and a rigid current collector, which creates a plurality of contact points on the electrocatalytic sheet, and the membrane, electrocatalytic sheet and current collector are pressed by the electrolyte and / or elastic means of the electrolyzer.
