Kurzfassung
For further commercialization of the proton exchange membrane fuel cell technology an improvement of the stability of commonly used Pt-based oxygen reduction reaction (ORR) catalysts is necessary. In this study SnO2- and TiO2-carbon nanocomposites using high surface area Black Pearls (BP) and commercial metal oxide nanoparticles were investigated as support materials for Pt. Homogenously distributed 40 wt.% Pt catalysts were obtained. When using TiO2-BP support an outstanding intrinsic activity but no stability improvement was observed, whereas the use of SnO2- BP as Pt support lead to a slightly lower ORR activity but an increased catalyst stability.
