Proton Leakage Through Polyether-Sulfone Anion Exchange Membrane
The proton leakage through polyether sulfone anion exchange membrane was investigated. In the system containing hydrochloric acid or sulphuric acid on the cathodic side and the mixture of acid with alkali salt solutions on the anodic side was performed. The effect of alkali salt solutions was examined as a function of mole fraction in the anodic side. The proton leakage on the membrane is quantified from proton transport number value. The proton leakage was found to be higher for sulphuric acid compared with hydrochloric acid.
