1. A method of preparing a carbon nanofiber for a fuel cell electrode, the method comprising:

  • hydrolyzing a surface of a carbon nanofiber precursor with a hydroxide solution having a concentration from 0.05-1 M to form a hydrolyzed carbon nanofiber precursor;

    washing the hydrolyzed carbon nanofiber precursor with a hydrochloric acid solution to form a washed carbon nanofiber precursor; and

    sintering the washed carbon nanofiber precursor to obtain a carbon nanofiber, and wherein the carbon nanofiber is part of the fuel cell electrode.
