Abstract

A bipolar electrode has plate-like anode and cathode parts. The anode and cathode parts are secured together, edge-to-edge, to form a single element in one plane by an intermediate connecting piece. The intermediate connecting piece itself is a composite element having parts of materials which are compatible with the respectively adjacent anode and cathode. The two parts of the composite element are joined together by hot isostatic pressure, explosion-plating or diffusion-welding into the composite body, the resultant composite body then permitting welding of the respective anode and cathode plates to the respective anode part and cathode part of the composite element or body.
