| Abstract | ||||
| Conventional fuels have been severe impact on environment, therefore renewable sources are considered very good alternative to conventional one. Fuel cell have been considered to be an excellent power source of alternative energy. Platinum and its alloys have long been regarded as the best catalyst for oxygen reduction reaction in fuel cells at current stage of the technology. Platinum is highly expensive for cathode catalyst, the objective of this work is to synthesis and characterization of non-precious metallic nanostructures as novel, cheap and effective cathode catalysts for fuel cells. Cobalt- doped carbon nanofibers (Co-doped CNFs) as cathode catalyst for fuel cell, has been prepared and characterized by TEM and XRD measurements the oxygen electroreduction activity was studied by cyclic voltammetry (CV), thus results indicated that (Co-doped CNFs) has high current density for the reduction in fuel cell where it is cobalt only not iron-cobalt or Platinum cobalt alloy so (Co-doped CNFs) has high oxygen reduction reaction (ORR) activity. | ||||
