Bipolar metal electrode and electrolyser therewith

摘要

A bipolar metal electrode for the electrolysis of hydrochloric acid, comprising a nickel alloy cathode plate (20) and an anode structure in the form of a titanium mesh (36), the titanium anode mesh (36) being connected to a titanium backplate (22) by means of a plurality of titanium supports (34) and the titanium backplate (22) being spaced from the nickel alloy cathode plate (20) by an aluminium plate (24) which provides a hydrogen barrier and also acts as a current distributer.
