Galvanostatic investigation of electrochemical processes on RbCuCl I 4 3 2

Kinetics of electrochemical processes on the vitreous carbon electrode in contact with the solid electrolyte RbCu Cl I 4 3 2 has been investigated. In the interval of potentials from zero up to the decomposition potential of the electrolyte (0.57 V) the rate of the reversible electrochemical reaction Cu+ e ? Cu2+ is controlled by slowed diffusion of Cu2+ ions in the electrolyte. The diffusion coefficient of Cu2+ ions is equal to 1,5?10-8 cm2/s. The exchange current density of the electrode reaction is equal to 20?10-6 А/cm2.
