The invention discloses a carbon-carrier precious metal catalyst for fuel cell, a preparation method thereof and an application thereof. The catalyst uses band-shaped nanometer carbon as the carrier, sodium borohydride, methanol or glycol as a reducing agent, and co-reduces the band-shaped nanometer carbon and the precious metal acid or the precious metal salts to obtain the precious metal/band-shaped nanometer carbon catalyst for the fuel cell, preferably a platinum loading amount being 10-60 wt %. The catalyst is high in initial electrochemical active surface area, relatively small in current density attenuation during a chronoamperometry test, and relatively high in current density during an electrochemical timing current test compared with that of present catalysts, and shows relatively high electrochemical activity, relatively high current density and relatively excellent electrochemical stability.
