Title:
Measurement of oxygen reduction activities via the rotating disc electrode method: From Pt model surfaces to carbon-supported high surface area catalysts 
Abstract:
The aim of this report is to scrutinize the thin-film rotating disk electrode (TF-RDE) method for studying the electrocatalytic activity of high surface area catalysts. Special emphasis is given to the oxygen redn. reaction (ORR) on C-supported Pt catalysts. From measurements on 4 different Pt catalyst samples with various av. particle sizes, it is demonstrated in detail how the intrinsic properties of the catalyst, i.e., the mass activity (A/gPt) and the specific activity (A/m2Pt), are evaluate...    »
