This article is concerned with the fundamental and experimental overview of the rotating disc electrode (RDE) and rotating ring–disc electrode (RRDE) techniques. First, this review provides a brief discourse on the basic concepts and general descriptions of the RDE and RRDE techniques. Then, the theoretical derivation of the governing equations for the RDE and RRDE is described with the definition of the important kinetic parameters. Finally, the experimental applications of RDE and RRDE techniques to investigate the mechanism and kinetics of oxygen reduction at Pt‐dispersed carbon (Pt/C) electrodes for fuel cells are discussed in detail from a practical point of view.
