Griesheim Elektron cell

Griesheim (1) An early process for producing chlorine by electrolysis, developed by Chemische Fabrik Griesheim-Elektron, in Germany, and commercialized in 1890. The electrolyte was saturated potassium chloride solution, heated to 80 to 90°C. The byproduct potassium hydroxide was recovered. The process was superseded in the United States by several similar electrolytic processes before being ousted by the mercury cell, invented by H. Y. Castner and K. Kellner in 1892. See Castner-Kellner. 

There are other processes analogous to Castner s which involve no new principles and which are used to a limited extent for instance, with H. Becker s process 11 the form of the cell is modified and the contact electrode process of the Chem. Fabr. Griesheim-Elektron, where the cathode does not dip into the electrolyte but is merely in contact therewith.
