A method for producing a catalyst for a fuel cell comprising: a) injecting carbon particles into a fluidized bed reactor; b) evacuating the fluidized bed reactor to form a base pressure; c) introducing a catalytic metal precursor together with a carrier gas into the fluidized bed reactor to contact the catalytic metal precursor with the carbon particles; d d) purging a purge gas into the fluidized bed reactor; e) introducing a reaction gas into the fluidized bed reactor to attach the catalytic metal precursor to the carbon particles; and f) purging a purge gas into the fluidized bed reactor, wherein, the catalytic metal is attached to the carbon particles in a form of nano-sized spot.
