Abstract

A system comprising a thin electrolytic cell with nano-scaled inter-electrode gap has been analyzed, whereas counter-ions are pumped in the cell through a complementary electrode and they are blocked at the working electrode. The analysis has been performed by numerical solution of the classical transport equations in nonlinear regime. Essentially enhanced interface polarization and capacity are observed at the working electrode for cell thickness up to about ten Debye lengths. The polarization gain is proportional to the charge pump but becomes unstable with time for thicker cells.
