Single and coupled electrochemical bursters during the electrodissolution/passivation of iron

The ability to produce bursting electrochemical oscillations via the slow external variation of the applied potential is investigated during the electrodissolution/passivation of iron in sulfuric acid. The results are compared with those concerning spontaneous electrochemical bursting in the presence of chloride ions. Moreover, an assembly of two electrochemical Fe/H₂SO₄bursters is studied experimentally. The effect of phase space topology on synchrony is explored by studying the coupled response for different types of electrochemical bursters.
