NOVELTY - The electrode has a 20 to 120 pts. wt. polymer electrolyte binder including hydrogen ion conductivity. 1 to 80 pts. wt. carbon nanofibers contains a radical scavenger relative to 100 pts. wt. anode catalyst and 100 pts. wt. cathode catalyst. The anode catalyst contains platinum supported on a first carbon support in amount of 1 to 40 wt.% relative to total amount of the platinum and the first carbon support. The cathode catalyst contains platinum supported on a second carbon support in amount of 40 to 80 wt.% relative to total amount of the platinum and the second carbon support.    USE - Fuel cell electrode for use in a vehicle. Uses include but are not limited to a motor vehicles i.e. passenger automobile such as sports utility vehicles (SUV), buses, lorries, various commercial vehicles, watercraft e.g. boats and ships, aircraft, and hybrid vehicles e.g. gasoline-powered and electric-powered vehicles, electric vehicles, plug-in hybrid electric vehicles and hydrogen-powered vehicles.    ADVANTAGE - The electrode easily performs initial electrode coating process so as to prevent a catalyst layer from being lost even when deterioration of the catalyst layer occurs during long-term operation. The radical scavenger is added to the carbon nanofibers so as to prevent the radical scavenger from being lost from the catalyst layer and provide the carbon nanofibers with smaller particle size, thus significantly improving utilization of the radical scavenger. The cerium-zirconium oxide improves thermal stability of cerium nanoparticles, so that deformation and agglomeration of nanoparticles are reduced even under severe conditions.    DETAILED DESCRIPTION - The first carbon support and the second carbon support are selected from a group consisting of carbon powder, carbon black, acetylene black, Ketjen black, activated carbon, carbon nanotubes, carbon fibers, carbon nanowires, carbon nanohorns, carbon aerosol, carbon aerogel and carbon nanorings. The carbon nanofibers are carbon nanotubes, carbon nanowires, carbon nanohorns and carbon nanorings.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a membrane-electrode assembly during manufacturing process by coating a catalyst layer on a gas diffusion layer to form an electrode and bonding the electrode to a polymer membrane by thermal compression.
