WebWhen current is passed through an electrolyte to an ion selective surface (such as an ion-exchange membrane, micro/nanochannel junction or electrode), the passage of certain ions, and the rejection of others, generally lead to concentration variations and voltage losses (or internal resistance), known as \ion concentration polarization" (ICP).
