| Abstract: | Conductivity and transport properties of commercially available cation exchange membranes were investigated for their application in an electrochemical alkali concentrator. Among the three membranes studied, Nafion 961 was found to have high conductivity, high sodium ion transport and lower water transport characteristics which are the desired characteristics for fabrication of an alkali concentrator. The effect of concentration gradient between anolyte and catholyte on the overall transport properties is also reported.
