Abstract

Polarization measurements on specially prepared porous nickel electrodes were carried out in a half set-up to determine the intrinsic parameters (exchange current density and charge transfer coefficient) using the spherical grain model developed earlier. The values found for exchange current densities were (6 × 10^-6 to 2.8 × 10^-4 A cm^-2) higher than that reported in the literature which shows the superiority of this electrode. Exchange current density followed an exponential relation with temperature. Apparent activation energies were found to decrease with increasing overpotential and the activation energy corresponding to zero overpotential by extrapolation was found to be 31.4 kJ mol^-1.
