The index T denotes any direction tangential to the discontinuity surface. At the same time a closing relation is absent for the induced surface charge o which generates a need for the introduction of an impedance matrix Wei Hu Hong Guo 2002 Danae D. et al. 2002 Larruquert J.

Vesec I. et al. 2001 Broe I. Keller O. 2002 Keller 1995 Keller O. 1995 Keller O. 1997 . The induced surface charge o not only characterizes the properties of a surface but also represents a function of the process . o E ổE ổt H ỔH Ổt therefore the surface impedances Wei Hu Hong Guo 2002 Danae D. et al. 2002 Larruquert J. I. 2001 Koludzija B. M. 1999 Ehlers R. A. Metaxas A. C. 2003 are true for the conditions under which they are determined. These impedances cannot be used in experiments conducted under other experimental conditions. The problem of determination of surface charge and surface current on metal-electrolyte boundaries becomes even more complicated in investigating and modeling nonstationary electrochemical processes . pulse electrolysis when lumped parameters L C and R cannot be used in principle. We will show that o can be calculated using the Maxwell phenomenological macroscopic electromagnetic equations and the electric-charge conservation law accounting for the special features of the interface between the adjacent media. Separate consideration will be given to ion conductors. In constructing a .
