Abstract:
1. A method for manufacturing a membrane-electrode assembly, the method comprising: preparing a catalyst slurry for forming a fuel cell electrode; adding 1 to 80 parts by weight of carbon nanofibers containing a radical scavenger relative to 100 parts by weight of an anode catalyst containing platinum supported on a first carbon support in an amount of 1 to 40 wt % and a cathode catalyst containing platinum supported on a second carbon support in an amount of 40 to 80 wt % to the catalyst slurry, the carbon nanofibers containing the radical scavenger being added in the form of a slurry; stirring the resulting mixture to obtain a final catalyst slurry; coating the final catalyst slurry on a release paper to form an electrode; drying the electrode; and bonding the dried electrode to a polymer membrane by thermal compression and removing the release paper to obtain a membrane-electrode assembly.
