摘要：

Platinum catalyst was supported on single-wall carbon nanohorns (SWNHs) to demonstrate the suitability of SWNH's application to the electrodes of polymer-electrolyte fuel cells. The Pt particles were homogeneously dispersed on the SWNHs, and their particle size was about 2 nm. This size was less than half of that supported on conventional carbon black. A fuel cell using the SWNHs had a larger current density than one using the carbon black. (C) 2002 Elsevier Science B.V. All rights reserved.
