Sažetak

This paper reports the investigation of electrochemical phenomena
at an electrolytic junction of a rectifying system with
membranes, and the behaviour of such a system when current
flows through it in forward direction.
After formation of such a junction a potential difference
appears as it is to be expected. The nature of this potential difference
has been examined. When current flows through the system
in forward directdvn two processes take place, which are importa
nt for the overall resistance of the system: a cha nge in the
resistance of the thin layer of liquid between th~ membranes, and
a lowering of the potential difference between the membranes.
After the termination of a pulse it takes a certain »t ime ·of relaxation
« for the system t o return to its original state, i. e. to establish
the original potential difference between the membranes. This »time
of relaxation« depends on the l ength of the pulse and the intensity
of current use d.
