NOVELTY - The fuel cell electrode comprises 20-120 parts by weight of a polymer electrolyte binder having hydrogen ion conductivity, and 1-80 parts by weight of carbon nanofibers containing a radical scavenger relative to 100 parts by weight of an anode catalyst and relative to 100 parts by weight of a cathode catalyst. The anode catalyst contains platinum (1-40 wt.%) supported on a first carbon support, and the cathode catalyst contains platinum (40-80 wt.%) supported on a second carbon support. The carbon nanofibers consist of carbon nanotubes, carbon nanowires and/or carbon nanohorns.    USE - The fuel cell electrode is useful for manufacturing a membrane-electrode assembly (claimed), which is useful in motor vehicles such as passenger automobiles including sports utility vehicles, buses, trucks, commercial vehicles, watercraft including boats and ships and aircraft, hybrid vehicles, electric vehicles, plug-in hybrid electric vehicles, hydrogen-powered vehicles and other alternative fuel vehicles.    ADVANTAGE - The fuel cell electrode exhibits increased physical and chemical durability, and improved performance.    DETAILED DESCRIPTION - The fuel cell electrode comprises 20-120 parts by weight of a polymer electrolyte binder having hydrogen ion conductivity, and 1-80 parts by weight of carbon nanofibers containing a radical scavenger relative to 100 parts by weight of an anode catalyst and relative to 100 parts by weight of a cathode catalyst. The anode catalyst contains platinum (1-40 wt.%) supported on a first carbon support, and the cathode catalyst contains platinum (40-80 wt.%) supported on a second carbon support. The carbon nanofibers consist of carbon nanotubes, carbon nanowires, carbon nanohorns and/or carbon nanorings, and have a diameter of 5-100 nm. The radical scavenger comprises nanoparticles that have an average particle size of 1-20 nm and are added to the carbon nanofibers. An INDEPENDENT CLAIM is included for a method for manufacturing a membrane-electrode assembly.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a structure of a fuel cell electrode.
