EFFECTIVE DIFFUSION-COEFFICIENT IN ELECTROCHEMICAL SYSTEMS WITH MATRIX ELECTROLYTES

The effective diffusion coefficient in an electrolyte-containing porou s capillary matrix is considered as a function of a number of factors that determine operation of electrochemical devices with matrix electr olytes. The reasons for anomalously high effective diffusion coefficie nts are analyzed. The structure of an electrolyte-containing capillary membrane is shown to be related with the electrolyte concentration gr adient at the interface between the electrode and electrolyte-containi ng matrix.
