Efficient quaternary PtRuFeCo nanoparticles supported N-doped graphene as a bifunctional electrocatalyst for low-temperature fuel cells |
| 초록 |
In this study, N-doped graphene supported quaternary electrocatalyst (PtRuFeCo/NG) was synthesized and evaluated for potential oxygen reduction reaction (ORR) and methanol oxidation reaction (MOR) in low-temperature fuel cells. The maximum power densities achieved with direct methanol fuel cell (DMFC) and proton exchange membrane fuel cell (PEMFC) were 778 and 122 mW cm-2, respectively. Also, PtRuFeCo/NG showed 2- to 3-fold enhancement in ORR, MOR, DMFC, and PEMFC performances than that of the previously reported catalysts due to nitrogen doping into the graphene matrix in addition to the bifunctional, electronic and integrated synergistic effects of alloying low-cost Fe and Co with Pt and Ru. The PtRuFeCo/NG has high potential to be used as anode and cathode catalysts with great reduction in the processing cost of fuel cell which is the major problem facing the fuel cell industry. |
