Abstract
Stable hybrid support for platinum is prepared for polymer electrolyte fuel cells (PEFCs). The synergetic interaction between platinum and optimum level of iron and nitrogen co-doped into titania (TiONFe) framework moiety leads to superior cell performance and long-term stability as compared to platinum on carbon. Pt metal nanoparticles are deposited on TiONFe framework by colloidal method. Accelerated durability test (ADT) are performed for both Pt/C and Pt/TiONFe framework by potential hold at 1.2Â V. The corrosion stability is increased for platinum deposited on TiONFe framework in PEFC and retains 50% of cell performance even after 200Â h as compared to Pt/C with only 18% of cell performance for 80Â h. The degradation of catalyst and loss of cell performance are explained by various characterizations before and after ADT.
