Abstract
An improved hybrid bipolar electrode particularly useful in an alkali chloride electrolysis application, having an anodic member and cathodic member connected in spaced apart relationship by a fastener assembly, a seal being formed between portions of the anodic member and the cathodic member to substantially seal electrolyte from the space between the anodic member and the cathodic member. In one aspect, a barrier member is interposed between the anodic member and the cathodic member to inhibit the contact of migrating atomic hydrogen with the anodic member. In one other aspect of the present invention, a portion of the fastener assembly is constructed of an electrically conductive material and electrical continuity is established between the anodic member and the cathodic member via the fastener assembly, the barrier member serving to effectuate a more even distribution of current flow between the cathodic member and the anodic member in yet another aspect of the present invention.
