Prolonged cycles at high temperatures cause damage to the electrode coating.
Does a long cycle time have an impact on the membrane?
It’s mainly the changes in the concentration of the electrolyte over time that have a significant impact on the ion membrane
The main purpose is to prevent a decrease in the alkali concentration and an increase in salt content within the cathode cycle. Additionally, during this process, due to the increased amount of water migration, as well as the difference in water permeability between the sulfonic acid layer and the carboxylic acid layer, significant pressure can develop between these two layers, which may lead to issues such as membrane delamination and bubbling.
