NOVELTY - This creation provides a carbon felt modification method and a carbon felt modification system. The modifying method includes: preparing carbon felt and modifying agent, wherein the modifying agent includes: inorganic acid, graphene, hydrocarbon, nitrogen-containing organic compound, metal compound or a combination thereof; atomizing the modifying agent to obtain the modifying agent aerosol; and passing the modifier aerosol and the plasma carrier gas into the plasma generating device to generate a plasma beam containing the modifier aerosol, and spraying the plasma beam containing the modifier aerosol onto the surface of the carbon felt to form Modified carbon felt. The carbon felt modification system includes a working platform for placing carbon felt, a tank containing modifiers, an atomizing device for forming modifier aerosols, and a plasma beam containing modifier aerosols The plasma generating device sprays the plasma beam containing modifier aerosol onto the surface of the carbon felt to form a modified carbon felt.
