Platinum supported on carbon nanotubes (CNTs) with different tube diameters <10, 10-20, 40-60 and 60-100 nm were prepared. The catalysts were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD). The metal particle size for 40 wt pct Pt catalysts were 2-5 nm. Self-prepared Pt/CNTs catalysts and purchased Pt/XC-72 were studied by polarization curves, and it was found that in the H2/O2 fuel cell system, Pt supported on Vulcan XC-72 (Pt/XC-72) possessed higher catalytic activity than Pt/CNTs. But in H2/air system, Pt supported on CNTs with diameter 10-20 nm (Pt/CNT1020) possessed higher activity than other Pt/C catalysts.
