Abstract:
SnO 2 doped with Sb and Nb has been investigated for its use as catalyst support materials replacing carbon to enhance PEM fuel cells stability. Nanostructured powders of various doping levels were prepared by flame spray pyrolysis (FSP). The specific requirements of surface area 〉 50 m 2 g −1 and electronic conductivity 〉 0.01 Scm −1 were obtained, and pore sizes ranging mainly from 10 to 100 nm. Pt particles (9–20 wt.% in loading targeted) of ~1 nm well dispersed in Sb-doped SnO 2 was prepared by a one-step FSP procedure providing microstructures of high interest for further investigations as cathode in PEM fuel cells.
