ABSTRACT:
A method and an apparatus for controlled, low current start-up of one of an electrical series of membrane electrolytic cells in which the currents through all but one of the remaining cells of the electrical series are unaffected. The method involves placing the cell to be started-up in electrical series with a variable resistor and placing the cell and resistor combination in parallel with the following or preceding one of the remaining cells in the electrical series and then slowly decreasing the resistance of the variable resistor over a preset time period so as to gradually increase the current to the cell being started up and finally eliminating the variable resistance altogether and reconnecting the cell being started-up in electrical series with the remaining cells.
