• The effect of methanol and ethanol cross-over on the performance of PtRu/C-based anode DAFCs 

      Song, S.; Zhou, W.; Liang, Z.; Cai, R.; Sun, G.; Xin, Q.; Stergiopoulos, V.; Tsiakaras, P. (2005)
      In the present work, the cross-over rates of methanol and ethanol, respectively, through Nafion®-115 membranes at different temperatures and different concentrations have been measured and compared. The changes of Nafion®-115 ...
    • The effect of the MEA preparation procedure on both ethanol crossover and DEFC performance 

      Song, S.; Wang, G.; Zhou, W.; Zhao, X.; Sun, G.; Xin, Q.; Kontou, S.; Tsiakaras, P. (2005)
      In the present work, the changes of Nafion((R))-115 membrane porosity in the presence of ethanol aqueous solutions of different concentrations were determined by weighing vacuum-dried and ethanol solution-equilibrated ...

      Song, S.; Zhou, W.; Tian, J.; Cai, R.; Sun, G.; Xin, Q.; Kontou, S.; Tsiakaras, P. (2005)
      In the present work, Nafion (R) membrane porosity changes were determined in aqueous ethanol solutions with different concentrations by weighing vacuum-dried and ethanol aqueous solution equilibrated membranes at room ...
    • Hydrogen production over a commercial Pd/Al2O3 catalyst for fuel cell utilization 

      Goula, M. A.; Kontou, S.; Zhou, W.; Qin, X.; Tsiakaras, P. E. (2003)
      In order to produce a hydrogen stream for fuel cell utilization, the study of the ethanol steam reforming process over an alumina supported palladium commercial catalyst was carried out. The effect of the reaction temperature, ...
    • Pt based anode catalysts for direct ethanol fuel cells 

      Zhou, W.; Zhou, Z.; Song, S.; Li, W.; Sun, G.; Tsiakaras, P.; Xin, Q. (2003)
      In the present work several Pt-based anode catalysts supported on carbon XC-72R were prepared with a novel method and characterized by means of XRD, TEM and XPS analysis. It was found that all these catalysts are consisted ...
