Abstract
| - A method is described for the study of the kinetics of electrode reactions on the basis of analytical solutionsof three transient electrochemical processes comprising the diffusion of ions in electrolyte, charge-transferreactions, and a charging process of an electrochemical double layer. Multipulse currents are applied to aworking electrode of (110) single-crystalline nickel in nickel sulfamate, and the potentials between the workingand counter electrodes are recorded. The measured potential−time curves well agree with those predicted bythe analytical solution. The kinetic constant, exchange current density, and double-layer capacitancecharacterizing the kinetics of the electrode reactions are determined from the measured potential−time curvesusing the analytical solution.
