Abstract An electrochemical investigation on the oxygen reduction under thin electrolyte layer was made usingKelvin probe as reference electrode.It was found that as the electrolyte layer thickness decreased duringelectrolyte evaporation,the rate of oxygen reduction first increased,then stagnated and finally decreased,thus showing a maximum.Althougy oxygen salting out effect had some influence on the rate of oxygenreduction,it was not main cause responsible for the decrease in cathodic limiting current in the case ofvery thin electrolyte layer. With decreasing water layer thickness upon drying, the oxygen reduction ratewas in trun accelerated by the faster oxygen diffusion, hindered by the limited rate of oxygen dissolutionat the gas/liquid interface, and reduced due to nonuniform current distribution on electrode surface as thewater layer thickness became very thin.
