- Charge Transfer Resistance - an overview | ScienceDirect Topics
Charge transfer resistance (Rct) is the resistance of ion transferring from a solvated ionic state in the electrolyte crossing the electrode electrolyte interface and inserting into the electrodes, which causes the activation polarization [119] The charge transfer resistance can be studied using electrochemical impedance spectroscopy (EIS)

The EIS patterns are tted with an EC consisting of a solution resistance Rs in series with two (R, Q) elements; the obtained values of charge-transfer resistance (Rct) and mass-transfer resistance (Rd) are shown in Table S3
- Charge-transfer Resistance - Gamry
Stirring minimizes diffusion effects and keeps the assumptions of CO = CO * and CR = CR * valid When the overpotential, η, is very small and the electrochemical system is at equilibrium, the expression for the charge-transfer resistance changes into: From this equation the exchange-current density can be calculated when Rct is known
