摘要

The formalism related to alternating current-voltage methods is reviewed, completed and unified for hydrogeninsertion in metals and alloys, in relation to permeation cell membranes with potentiometric or potentiostatic detectionof hydrogen and electrodes with impermeable boundary conditions. The electrochemical system representeation interms of an electrical dipole or quadripole is first given to introduce the impedance onthe entry side, the transfer impedances and the potential and current density transfer functions through the membranes, which can be used expeirmentally to investigate hydrogen insertion. Next, the surface process is presented, taking the direct (one-step) insertion mechanism into consideration for the sake of simplicity. Based onthe surface process anddiffusion formalisms, theoretical expressions are derived for the entry side impedance, transfer functions and transfer impedances, depending onthe electrode or membrane type and the boundary conditions.
