Abstract
The hydrogen overpotential on fine silver cathodes has been determined from 2 to 35° and over a current density range from 0.03 to 2000 μa cm−2. Two Tafel slopes were observed, RT/F at low currents, 2RT/F at high currents. The stoichiometric number was found to be one and the symmetry factor one-half at low currents. The heat of activation changed from 18.8 kcal at low currents to 14.3 at high currents.Keywords
