摘要：

The aim of this work was to study the effect of cobalt addition on the rate of hydrogen effusion reaction, in Fe-Co based amorphous alloys. Different techniques were used. Polarization measurements show that the addition of cobalt to Finemet alloys results in an increase of the catalytic activity of the base material. On the other hand, comparative measurements have been carried out by electrochemical impedance spectroscopy (EIS), on different amounts of cobalt in electrodes. Despite the instability of the system, Volmer-Heyrovsky mechanism is proposed to explain the process. (C) 2001 Elsevier Science B.V. All rights reserved.
