![عکس صفحه اول مقاله: The evaluation of the polarization resistance in a tubular electrode and its application to the hydrogen electrode reaction The evaluation of the polarization resistance in a tubular electrode and its application to the hydrogen electrode reaction](/preview/png/196414.png)
An alternative method for the determination of the kinetic parameters involved in the elementary steps of the reaction mechanism of the hydrogen electrode reaction is proposed. It is based on the determination of the variation of the polarization resistance in a tubular platinum electrode with a laminar flow of electrolyte as a function of the activity of protons of the electrolyte solution. A theoretical expression that relates the experimental variables and the equilibrium polarization resistance is developed, which takes into account the current distribution along the electrode surface. The results are compared with others obtained previously, contributing to the verification of the kinetic mechanism through a completely different experimental procedure.
