Instability of Supported Platinum Nanoparticles in Low-Temperature Fuel Cells
نویسندگان
چکیده
This paper discusses the mechanisms of surface area loss of supported platinum (Pt) electrocatalysts in lowtemperature fuel cells. It is argued that submonolayer dissolution of Pt nanoparticles governs the surface area loss at high voltages by increasing the loss of Pt from carbon and coarsening of Pt nanoparticles on carbon.
