<br/>Electrocatalysts without precious metals are being actively studied in the field of electrochemical devices, including fuel cells due to their low cost and electrocatalytic activity. Graphene, a new 2-dimensional sp<sup>2</sup>-hybridized hexagonal (honeycomb lattice) carbon material, provides the noticeable replacing opportunity as an electrocatalyst for oxygen reduction reaction (ORR) because of its excellent chemical, electrical and thermal properties, high catalytic activity, and tolerance against poisoning. In this study, a nitrogen-doped reduced graphene oxide (N-rGO) catalyst for oxygen reduction reaction (ORR) of hydrogen membrane fuel cell was investigated. This process, in this study provides an effective yield and is free of impurities, resulting in the intrinsic catalytic performance. The surface morphology, hydrophobicity and electrical conductivity of the synthesized N-rGO was analyzed by BET and UV-visible spectroscopy. A graphene oxide-hydrogen membrane fuel cells that does not use Pt/C was prepared using the N-rGO electrode and the graphene oxide composite electrolyte membrane modified with 3-mercaptopropyl trimethoxysilane developed in the previous study, and its performance is reported.
