제목 | Enhanced activation of Pt/C electrocatalyst for PEMFC via N-functionalization of carbon support |
초록 | Oxygen reduction reaction (ORR), due to its slow and complex reaction kinetics, is considered as the performance-hindering step in PEMFC. A wide range of studies has thus been studied to improve PEMFC performance by modifying ORR catalyst structure and composition. N-functionalized carbon is known to possess high affinity with metal precursors. In this study, we have functionalized nitrogen on carbon support to use as an anchor site for Platinum loading to achieve high dispersion of Platinum particles. Thereby synthesized Pt/N-C catalyst was expected to show enhanced performance in ORR. Three-electrode half-cell test was performed to confirm the enhanced ORR activity of the catalyst. The catalyst was also applied to full cell environment and the electrochemical analysis was conducted to verify the improved ORR activity versus conventional Pt/C catalysts on a real-life operating condition. |
