✦ Synopsis

Sustained potential oscillations were observed in a certain range of anodic current, during the oxidation of H, in various acidic solutions with a small amount of a metal ion, such as Ag+, Cu* + and Pb* +, and the following results were obtained. The maximum potentials in oscillations are linear to the logarithm of the anodic current but are scarcely dependent on the concentration of metal ion. A smaller bubbling rate of H, results in a higher maximum potential and a longer periodic time.

The mechanism of the oscillation is discussed qualitatively.
