Abstract
An electrode for electrolysis comprisng an electrically conducting metal, the surface of which is embossed with at least one central, vertical circulation channel (2) and upwardly directed channels (1) in a herring-bone pattern, the upwardly directed channels (1) forming an angle of <90.degree. with a horizontal line in the plane of the electrode surface and communicating with the centrally positioned, vertically directed circulation channel (2). The circulation channel (2) may be provided with penetrating slits or holes (3). The electrode may be used for electrolysis in a membrane cell, for electrochemical recovery of metals, or for recovery of chlorine from sea-water. The electrode can be manufactured by embossing the surface through stamping with a die or through rolling with a figure roller.
