  • Patent number: 3994798
    Abstract: Novel bipolar electrodes are provided. Such electrodes include an anode in the form of a plate, which is made of a suitable anodic metal, e.g. platinum plated titanium. The cathode is also in the form of a metallic plate and also is formed of a suitable cathodic material, e.g. steel. The anode and cathode are joined to, but separated by, a generally U-shaped (in cross-section) median electrode plate formed, e.g., of titanium. A plurality of electrically insulating spacer elements, formed of a suitable plastics material, e.g. polyvinyl dichloride, project outwardly from both flat faces of at least the cathode plate by also if desired, from the anode plate. A bipolar electrolytic cell fitted with these novel bipolar electrodes has improved current efficiencies, leading to improved electrolyte flow, minimal gas entrapment, less overheating and improved operating load factors.
