NOVEL ELECTROLYZER HAVING MEANS FOR ELECTRICALLY CONNECTING VALVE METAL ANODE RIBS AND CATHODICALLY RESISTANT METAL CATHODE RIBS

摘要

An electrolyzer having means for electrically connecting valve metal anode ribs and cathodically resistant metal cathode ribs through a bipolar plate comprising a valve metal sheet on the anode side and steel plate on the cathode side of the bipolar plate, bimetal strips with a valve metal side and a copper side to which at least one copper threaded stem is welded, inserted into grooves cut on the steel plate side opposite to the valve metal sheet with the copper threaded stem emerging through a hole through the bottom of the grooves of the steel plate, steel nuts screwed on the copper threaded stems from the cathode surface of the steel plate to provide a leak-proof connection, and the ribs and the valve metal sheet welded on the valve metal side of the bimetal strips being inserted into the grooves of the steel plate and the cathodically resistant cathode ribs being welded to the said steel nuts.
