Kinetic Model of Platinum Dissolution in PEMFCs

This paper presents a mathematical model of oxidation and dissolution of supported platinum catalysts in polymer electrolyte membrane fuel cells (PEMFCs). Kinetic expressions for the oxidation and dissolution reactions are developed and compared to available experimental data. The model is used to i...

Summary:This paper presents a mathematical model of oxidation and dissolution of supported platinum catalysts in polymer electrolyte membrane fuel cells (PEMFCs). Kinetic expressions for the oxidation and dissolution reactions are developed and compared to available experimental data. The model is used to investigate the influences of electrode potential and particle size on catalyst stability.
