The difference between unipolar and bipolar electrolyzers
Thread Content
This post was last edited by sunjl1981 on 2013-1-6 23:16. We only have bipolar types here; I’m interested in knowing about the unipolar types. In the bipolar type, a membrane is placed between the anode and cathode areas and then secured with screws to form a single unit slot. So where is the membrane in the unipolar type? Are two membranes installed, one for each pole? #hcbbs
It’s better to learn about ion-exchange membrane soda-making technology first; otherwise, the moderators will have objections if you post requests for help.
It can be seen that the electrolytic cells you use are independent units; they are either from Woody or INEOS. A bipolar cell refers to a cell that has both a cathode and an anode on the same unit, hence the term \"bipolar\". A unipolar cell, on the other hand, has only one type of electrode per unit – either a cathode or an anode. The conductivity patterns of unipolar and bipolar cells differ; reading more books will help you understand this better
The biggest difference is that the repolarization grooves are connected in series; the entire unit must be shut down for maintenance； The monopolar slots are connected in parallel, allowing for individual shutdown during maintenance without affecting production.
Monopolar and bipolar are classified according to the power supply method of the electrolyzer. Inside a single-pole slot, the DC power supply circuits are connected in parallel; therefore, the sum of the currents flowing through each individual slot constitutes the total current of that single-pole slot. The voltage across each individual slot is equal, which means that the characteristic of a single-pole slot is operation at low voltage with high current. Polarization cells are the exact opposite: the circuits of each individual cell are connected in series, so the current is the same across them. However, the total voltage of the electrolyzer is the sum of the voltages of all the individual cells. Therefore, polarization cells are characterized by operation at low currents and high voltages.
