It depends on how long the single slot operates at high slot pressure Compare with the operating time of other unit slots. Possible reasons include: 1. The concentration of the alkaline solution is too high, causing the ion exchange membrane to bubble and get damaged. 2. Poor circulation of the anode solution and cathode solution in the single tank. OP, what are the indicators for gas purity?
During inspection, it was found that the cell slot voltage of a single cell was much higher than those of the surrounding cells; it was necessary to check whether the inlet and outlet fluids were flowing properly and whether there were any blockages.
It would be best to be able to provide information on the current and cell voltage levels, to facilitate analysis. If the import and export traffic is normal, the problem isn’t serious.
This can also occur due to ion membrane leakage
First, check the flow rates at the anode and cathode outlets. Then consider whether the polar net is deformed.
It’s also possible that the electrode has corroded.
1. Clogged feed pipe 2. Deformed anode and cathode meshes 3. Peeling coating. It depends on whether the increase is sudden or gradual; it’s easier to analyze in such cases. If the increase is sudden, option one is more likely to be the cause

You can stop, disassemble the unit slot and check it, and you’ll know
