Finally, the more even current lines over the length of the cathode blocks are expected to decrease the erosion rate.(plate) Analysis of the current distribution in an aluminum collector bar for electrolysis(steel) Conventional cells use the cathode-collector-bar assembly to carry the current through molten aluminium, the cathode and the steel collector-bar to nearest external bus. The electrical conductivity of the steel is so poor relative to the molten aluminium that the outer third of the collector bar carries the maximum load, which in turn increases the horizontal components of the current within the cell.(plate) Author Ahmet Oguz TezelOptimization of porous current collectors for PEM water collector bar for electrolysis(steel) Jun 01, 20091..
