Abstract

Harmonics current measurements were conducted on YSZ/M(Pt, Au), O2 electrochemical reaction and the results were compared with ac impedancedata. It was found that the processes which are not distinguishable from each other by AC impedance measurement alone because of their almost identical time constant can well be discriminated by the harmonics current analysis. Platinum and gold electrodes showed very dissimilar harmonics current spectrum and it was concluded that the major difference in electrode behavior between gold and platinum comes from the difference in the surface diffusivity of adsorbed oxygen atoms.
