    • Benzene electro-oxidation in a PEMFC for phenol and electricity cogeneration 

      Cai, R.; Song, S.; Ji, B.; Yang, W.; Xin, Q.; Sun, G.; Douvartzides, S.; Tsiakaras, P. (2005)
      In the present investigation, the electrochemically-assisted oxidation of benzene in a H2-O2 proton exchange membrane fuel cell (PEMFC), for electricity and phenol cogeneration is studied. Experiments were carried out in ...

    • Direct methanol fuel cells: Methanol crossover and its influence on single DMFC performance 

      Song, S. Q.; Zhou, W. J.; Li, W. Z.; Sun, G.; Xin, Q.; Kontou, S.; Tsiakaras, P. (2004)
      In the present investigation, the methanol crossover rate through Nafion((R))-115 membrane at different temperatures and different concentrations had been investigated in a fuel cell test apparatus by using gas chromatography ...

    • 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 ...

    • Ethanol crossover phenomena and its influence on the performance of DEFC 

      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 ...

    • 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 ...

    • Pt-based catalysts for direct ethanol fuel cells 

      Song, S.; Xin, Q.; Sun, G.; Tsiakaras, P. (2004)
      A PtSn/C catalyst was synthesized by the direct decoration of commercial Pt/C with Sn as anode electrocatalyst in direct ethanol fuel cell (DEFC). The techniques of cyclic voltammetry, anode polarization curve, and single ...
