Abstract
Provided is a fluorine-doped tin oxide support, a platinum catalyst for a fuel cell having the same, and a method for producing the same. Also described is a high electrical conductivity and electrochemical durability by doping fluorine to the tin oxide-based support through an electrospinning process. Thus, while resolving a degradation issue of the carbon support in the conventional commercially available platinum/carbon (Pt/C) catalyst, what is designed is to minimize an electrochemical elution of dopant or tin, which is a limitation of the tin oxide support itself and has excellent performance as a catalyst for a fuel cell.
