ABSTRACT

Carbon nanofiber (CNF) grown catalytically was chemically activated with KOH to attain structural change of CNF.BET, it was found that KOH activation was effective to develop particular sizes of pores on the CNF surface, increas-ing the surface area of CNF. Activated CNF was aplied as an anode catalyst support of fuel cell. The efects of difer-ent activation conditions including the activation temperature and the activation time on the specific surface area of theCNF activated with KOH were investigated to obtain appropriate structure as a catalyst support. The 60 wt% Pt-Ru cat-alyst prepared was observed by using TEM and XRD.
