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 ...

How far are direct alcohol fuel cells from our energy future?

Song, S.; Maragou, V.; Tsiakaras, P. (2007)
