ハルセルにおける一次電流分布の均一化

Abstract

By the analogical method using the conducting paper, cell voltage and current distributions at electrodes in Hull cell are measured as a function of the cathode inclination angle (α) and the distance between anode and cathode electrodes. The effect of auxiliary anode and cathode, and current shield on the current distribution at cathode in Hull cell and Cell voltage are also measured. The current distribution at cathode is expressed as a straight line on the semi-log plot for the current vs. distance along the cathode only in the case α=39°. The longer the distance between electrodes, the higher the cell voltage, eventhough the distance between electrodes has little effect on the current distribution at cathode. The auxiliary cathode and shield scarcely improve the current distribution at cathode and only increase the cell voltage.
