What is the effect of excessively high or low pressures of chlorine and hydrogen on the cell voltage?

Hello, sea friends. What impact does an excessively high or low pressure in the chlorine main pipe or the hydrogen main pipe have on the cell voltage? What impact does an excessive accumulation of chlorine in the tank have on it?
In ion-exchange membrane electrolyzer systems, there are interlocks in place to prevent excessively high or low pressures of chlorine and hydrogen; therefore, it is necessary to keep these pressures within the specified ranges during normal operation. In principle, as the chlorine pressure increases, the voltage increases; conversely, when the pressure decreases, the voltage decreases. As the hydrogen pressure increases, the voltage decreases; as the pressure decreases, the voltage increases. In fact, the anode-cathode system features automatic valves for cascade control of the pressure difference, so the pressure difference should not change significantly. Chlorine remaining in the electrolyzer can damage the ion membrane, causing bubbles, pinholes, and other defects.
