Abstract
A power lead for electrodes in electrochemical cells has a core of a material, such as copper, that has good electrical conductivity; the core is surrounded with large-area contact by a tubular titanium body, and the surface remote from the core of the titanium body is connected to the electrode. The titanium body has an opening through which a titanium retaining pin is introduced into a recess of the core, and the rim of the opening is welded in a hermetically sealed manner to the metal pin. A preferred application is the construction or repair of anodes for diaphragm cells.
