Abstract
Electrolyzer for the electrolysis of a solution of a salt for the production of a solution containing an acid and a solution of a base, said electrolyzer comprising at least one elementary cell divided into three compartments by two cation-exchange membranes, the first of said compartments contains the first of said membranes and a cathode for hydrogen evolution and the production of the base, a central compartment is defined by said cation-exchange membranes and has an inlet for the solution of the salt and has an outlet for the withdrawal of the solution containing the acid, a third compartment contains the second of said cation exchange membranes and an anode, said anode comprises a porous electrocatalytic sheet for hydrogen ionization and a porous rigid current collector, said third compartment further has an inlet for a hydrogen-containing gaseous stream and an outlet for the venting of the rest of gas characterized in that said current collector has a multiplicity of contact points and said porous electrocatalytic sheet is flexible and is held in contact with said second membrane and said rigid current collector by pressure without bonding.
