The principles and theories of a channel flow double electrode （CFDE） and a rotating ring disk electrode （RRDE） were explained as examples of hydrodynamic electrochemical method. In addition, some applications of CFDE to corrosion mechanism analysis were introduced. The contents of this article are presented as follows.
Principle of channel flow double electrode （CFDE）
Principle of rotating ring-disk electrode （RRDE）
Measurement of diffusion limiting current in reversible electrochemical system
Anodic dissolution of copper electrode
Real-Time Surface Observation CFDE cell
