Abstract
Disclosed is a novel cellulose electrode having high performance, which is capable of substituting for carbon paper used as a conventional fuel cell electrode. A method of manufacturing the cellulose electrode includes cutting cellulose fibers to a predetermined length and binding the fibers, or directly weaving the fibers, thus producing a cellulose sheet, directly growing carbon nanotubes on the cellulose sheet, and supporting a platinum nano-catalyst on the surface of the carbon nanotubes using chemical vapor deposition. An electrode including the cellulose fibers and use of cellulose fibers as fuel cell electrodes are also provided. As a novel functional material for fuel cell electrodes, porous cellulose fibers having micropores are used, thereby reducing electrode manufacturing costs and improving electrode performance.
