FUEL CELL CATALYST, METHOD FOR PREPARING THE SAME, AND FUEL CELL COMPRISING THE SAME

A fuel cell catalyst including a conductive carrier and core-shell nanoparticles supported on the carrier. The core includes platinum and a transition metal and the shell includes a secondary metal. An electrochemical specific activity measured at a voltage of 0.05 V to 1.05 V (vs. RHE) in a potential range, at a scan rate of 5 mV/s and a rotation rate of 1,600 rpm in an O-saturated 0.1 M HClOelectrolyte solution is 0.3 mA/cm2 to 0.6 mA/cm2, and a mass activity is 0.05 mA/μg to 0.08 mA/μg.
