  • Method for ensuring and monitoring electrolyzer safety and performances
    Patent number: 8152987
    Abstract: There is described a method for ensuring and monitoring electrolyzer safety and performances in a manufacturing process which uses at least one electrolyzing cell containing at least one cathode and at least one anode separated by a membrane, comprising the step of: determining a safe single voltage operation range depending of the current and corresponding to the normally working electrolyzing cell; determining a reference voltage deviation depending on the time derivation of the current; measuring the voltage over time at the terminals of the electrolyzing cell; determining the measured voltage deviation by calculating the time derivative of the measured voltage; comparing the measured voltage to the safe single voltage operation range and the measured voltage deviation to the reference voltage deviation over time; stopping the manufacturing process when the measured voltage is outside the safe single voltage operation range or the difference between the measured voltage deviation and the reference voltage
