Abstract

ANY heterogeneity in the pore structure of an ionic membrane, such as differences in pore width, charge density at the pore walls, or the sign of these charges, renders the membrane electrochemically a mosaic1. When such a mosaic membrane is interposed between two electrolytic solutions of different composition its different parts will ordinarily give rise to different potentials. Consequently, the various parts of the mosaic interact electrically; spontaneous local circuits arise, somewhat analogous to those causing metal corrosion1–3.
