Fuel cells (FCs) are attracting much more attention for their potential as clean and mobile power sources in the future. It is reported that the conductivity, specific surface area, and pore structures of catalyst supports are key factors that determine their electrochemical activity. However, the effects of the structure of various carbon support materials have not fully studied to our best knowledge. In this work, herringbone-type carbon nanofibers-coated activated carbon fibers were prepared as a new potential material by a simple method of atmospheric pressure Ar/O2 plasma treatment on activated carbon fibers. The plasma treatment was varied with inputted powers at fixed Ar/O2 ratio and time. The pore structure of the samples was analyzed by N2/77K adsorption isotherms. |
