Abstract: An electrolytic cell comprising a walled enclosure including a cathode sidewall has busbar structure external to the cell. The busbar structure can include a gird bar releasably secured at the sidewall. It also may include a foraminous interface member between the gird bar and the sidewall, as well as have a small cathode busbar member on the sidewall. The small busbar member is typically located above and adjacent to the gird bar. Particularly when the gird bar and foraminous interface member are present, there can be internal support members for the cathodes directly secured to the inside face of the cathode sidewall. Furthermore, intercell connection may be handled directly to the outside face of the cathode sidewall. The overall structure can provide reduced potential for sidewall stress corrosion cracking, reduced cathode manufacturing cost, and accommodation of stress relief for the cathode weldment.
