Dissolution of platinum: limits for the deployment of electrochemical energy conversion?

Angew Chem Int Ed Engl. 2012 Dec 7;51(50):12613-5. doi: 10.1002/anie.201207256. Epub 2012 Nov 4.


Platinum stability: Dissolution of Pt, which is one major degradation mechanism in, for example, hydrogen/air fuel cells, was monitored under potentiodynamic and potentiostatic conditions. The highly sensitive and time-resolving dissolution monitoring enables the distinction between anodic and cathodic dissolution processes during potential transient and chronoamperometric experiments, and the precise quantification of the amount of dissolved Pt.
