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.

Fuel cell catalyst, method for preparing the same, and fuel cell comprising the same

Provided is a garment generating electricity which transforms kinematic energy generated when a user wearing the garment walks and/or swings arms past torso to an electric energy, and has a simple structure and is produced at low cost, and realizes excellent electricity generation efficiency. A garment generating electricity from ambulation or aim swinging past torso or both includes a magnet member arranged on a first part of a garment to generate magnetic field, a coil member provided on a second part of the garment which reciprocally moves with the first part of the garment while walking or swinging aims past torso, the coil member generating electricity from the magnetic field of the magnet member, and a storage battery charged with the electricity generated by the coil member.
