摘要：

Water dissociation effects in ion transport through anion exchange membranes with adhered cation exchange surface films are studied on the basis of a theory previously proposed for bipolar membranes. The effects that the adhered surface film exerts on the limiting current and on the electric current carried by the ions coming from water dissociation are found to be of particular relevance for the fouling phenomena observed in ion exchange membranes. Finally, some limitations of the theory concerning the use of the Onsager's theory of the second Wien effect to describe the electric-field-enhanced water dissociation are discussed.
