Degradation of perfluorinated sulfonic acid films: An in-situ infrared spectro-electrochemical study
Fang, X.; Shen, P. K.; Song, S.; Stergiopoulos, V.; Tsiakaras, P. (2009)The in-situ Fourier transform infrared (FTIR) spectro-electrochemical method was used to evaluate the degradation mechanism of perfluorinated sulfonic acid (PFSA) polymer for the first time. The effect of H 2O 2 concentration ... -
Direct alcohol fuel cells: A novel non-platinum and alcohol inert ORR electrocatalyst
Song, S.; Wang, Y.; Tsiakaras, P.; Shen, P. K. (2008)In the present investigation, a series of binary PdxFey/C electrocatalysts for the oxygen reduction reaction (ORR) was synthesized in a very short time by employing a pulse-microwave assisted polyol method. The physico-chemical ... -
High surface area tungsten carbide microspheres as effective Pt catalyst support for oxygen reduction reaction
Wang, Y.; Song, S.; Maragou, V.; Shen, P. K.; Tsiakaras, P. (2009)In the present work, the preparation of high surface area (256 m2 g-1) tungsten carbide microspheres (TCMSs) by the aid of a simple hydrothermal method is realized and the performance of the Pt electrocatalyst supported ...
