文摘

CNT-Pt/TiO2 has exceptional performance and stability at HT-PEMFCs cell test. Inorganic–carbon composite shows synergistic effects for good ORR activity. CNT and TiO2 cause a charge transfer phenomena offering more electrons to platinum. Interconnected nanofibrous catalyst has well organized paths for better transport.
