Method for ensuring and monitoring electrolyzer safety and performances
First Claim
1. 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, comprising the step of:
- determining a safe single voltage operation range depending on the current and corresponding to a normally working electrolyzing cell;
determining a reference single voltage deviation depending on the time derivation of the current;
measuring the single voltage over time at the terminals of the electrolyzing cell;
determining the measured single voltage deviation by calculating the time derivative of the measured single voltage;
comparing the measured single voltage of a cell with the safe single voltage operation range and the measured single voltage deviation of a cell with the reference voltage deviation and the measured single voltage deviation of a cell with the average voltage deviation of a group of reference cells over time; and
stopping the manufacturing process when the measured single voltage is outside the safe single voltage operation range or the difference between the measured single voltage deviation and the reference voltage deviation is outside a predetermined range or a single voltage behavior is different than the average of a group of reference cells.
