Abstract
Abstract A filter-press type electrolytic cell comprising alternatively arranged frames and diaphragms fastened together to form alternating anolyte compartments and catholyte compartments, wherein said frames comprise two oppositely disposed hollow members one of which has an inlet and the other an outlet for the flow of electrolyte solutions said inlet or outlet being on the outside surface thereof and each of said members having holes on the inside surface thereof which surfaces face each other, whereby the appropriate electrolyte is passed from said member having said inlet into the anolyte or catholyte compartment formed in the frame and the electrolyzed product is discharged from said anolyte or catholyte compartment into said member having said outlet.
