Comment on the paper "effect of stress on dissolution/precipitation of platinum: Implications concerning core-shell catalysts and cathode degradation in proton exchange membrane fuel cells" by Preethy Parthasarathy, Anil V. Virkar* [J. Power Sources 196 (2011) 9204-9212]

Research output: Contribution to journalLetter


Electrode potential of a metal changes by applied mechanical stress. This effect was experimentally determined both by Parthasarathy and Virkar [J. Power Sources 196 (2011) 9204-9212] and by the present authors [Phys. Chem. Chem. Phys, 3 (2001) 2662-2667]. The aim of the present Comment is to dispel a misunderstanding regarding the interpretation of the observations.
