Abstract

Graphene, produced by chemical vapor deposition (CVD) and modified with boron (B), cobalt (Co) and nitrogen (N), was investigated as electrocatalyst and support material for proton exchange membrane (PEM) fuel cells. Ammonia borane (H₃ N-BH₃) was used directly as doping agent while sodium borohydride (NaBH₄) was used indirectly. Samples were characterized, in addition to electrochemical methods, by scanning electron microscopy (SEM), X-ray photo-electron microscopy (XPS), Raman spectroscopy and XRD. While rotating disc electrodes (RDE) were used to characterize oxygen reduction reaction capacity of graphene electrodes, fuel cell testing was carried out with 5-cm² active area single cell. Boron based reduction of catalysts, compare to other approaches, have resulted 3 times higher current density reaching 3000 mA/cm² with PtCo/B/graphene catalyst in fuel cell testing.
