Current oscillation of copper electrode in acidic chloride solution was investigated using the channel flow electrode system. Phase space analysis of the oscillation shows the strange attractor and, moreover, the vending and streching behavior in the Poincare sections. The largest Lyapunov exponent of the current oscillation was positive. The above-mentioned results indicated that the oscillation was governed by deterministic chaos. Some reaction models of the two-valiable system were examined to represent the current oscillation. The current oscillation could be explained by the non-linear dissolution rate of the adsorbed intermediate, which was cubic autocatalysis.
