The oxygen reduction current in thin NaCl solution layer formed on zinc electrode was measured under an open-to-air to clarify the effect of solution layer thickness, and temperatures of environments and specimens on the oxygen transport behavior. The solution layer thickness was controlled by masking by organic tape with different thickness. Independent of temperature and solution layer thickness, a clear oxygen limiting current was observed. It was increased with reciprocal of solution layer thickness as the solution layer thickness became thinner than about 0.6 mm. It was clearly shown that combination of temperature of environment and specimen was important for oxygen transport behavior through thin solution layer.
