Dynamical and stationary analysis of an electrolyte diode and comparison with experiments

Stationary and non-stationary behavior of an electrolyte diode system is studied. The system consists of a microcapillary connecting two reservoirs with a strong acid and strong base. If an external electric field is imposed on the capillary, diode like current-voltage characteristics is observed. A...

Description
Summary:	Stationary and non-stationary behavior of an electrolyte diode system is studied. The system consists of a microcapillary connecting two reservoirs with a strong acid and strong base. If an external electric field is imposed on the capillary, diode like current-voltage characteristics is observed. A thin layer of electrolyte with extremely large pH gradient is formed in the closed regime of the diode. Transient behavior of the electrolyte diode is studied experimentally and numerically. Observed short-time overshoots of electric current in the current-voltage characteristics are explained based on numerical analysis of the reaction-transport processes in the capillary.
