Carbon nitride (CN x ) nanofiber is tested as a cathode catalyst in the direct formic acid proton exchange membrane (PEM) fuel cell at room temperature. CN x nanofiber is synthesized by electrospinning technique with polyacrylonitrile (PAN) as a supporting polymer and carbon black and Nafion ® dispersion as fillers. Potassium permanganate (0.144M) is used as oxidant, due to its higher reduction potential (1.7 V) as compared to O 2 . CN x nanofibers show fuel cell activity with current density (23 mA cm −2 ) and power density (6.77 mW cm −2 ) comparable to Pt black catalyst loading (43 mA cm −2 , 12.90 mW cm −2 ) at 300 mV.
