Abstract
The electrochemical oxidation of hydrogen on a platinum anode in the presence of copper ions exhibits under galvanostatic conditions kinetic oscillations due to periodic poisoning and activation transitions of the electrode by underpotential deposition and dissolution of a passivating Cu monolayer In the presence of chloride ions a transition to chaos from a stationary state via a Hopf bifurcation and a sequence of period doublings (Feigenbaum scenario) was observed upon increase of the current density. Further change of this control parameter caused a transition to another qualitatively different chaotic state through an interior crisis. Near the other end of the oscillatory region, this state evolved into periodic mixed-mode behaviour.
