【Abstract】 A review with 52 references is presented on varieties research methods for concentration observation and distribution in electrode diffusion layer. These methods depended on different principles, such as chemical analysis of resolving diffusion layer solution after fast freezing bulk electrolyte, absorption spectrometry and diffractive spectrometry based on the light absorbance change, interferometry and deflection spectrometry based on the refractive index change, Raman microprobe spectroscopy based on Raman spectroscopy and microelectrode probe based on electrochemical analysis. All of these methods are discussed from the aspects of principle, instrumentals, influence factors, features and application to electrochemistry. Perspective of this research direction is also discussed.更多还原
