| Abstract | In this chapter, to give readers the knowledge how to appropriately use rotating disk electrode (RDE) in their oxygen reduction reaction (ORR) study, fundamentals of both the electron transfer process on electrode surface and diffusion-convection kinetics near the rotating electrode are presented. Two kinds of RDE and their associated theories of the diffusion-convection kinetics and its coupling with the electron-transfer process are presented, one is the smooth electrode surface, and the other is the catalyst-layer-coated electrode. For measurements using the RDE method, the apparatus of RDE and its associated devices such as rotator and electrochemical cell are described to give the readers the basic sense about this technique. The measurement procedure including RDE preparation, catalyst layer fabrication, current-potential curve recording, the data analysis, as well as the cautions in RDE measurements are also discussed in this chapter. |
