Tóm tắt

An electric analog of an electrochemical cell is assumed to consist of a constant ohmic resistance, representing the bulk electrolyte, and a parallel combination of resistance and differential capacity, representing one interface. The response of the model to a rectangular current-time function is given in terms of circuit components. The interface parameters are not assumed to be constant and the equations yield instantaneous values for each of them. A pulse generator is described, which is capable of closely approximating the required current-time function. Results of measurements made on Pt and dropping Hg are presented.
