Fuel cell anode composed of Mo2C catalyst and carbon nanotube electrodes

Replacement of the normal Pt/C anode of a polymer electrolyte fuel cell (PEFC) with a Mo2C/CNT (carbon nanotube) electrode gave about half the voltage (below 600 mA/cm(2)). 2-20 nm Mo2C nanoparticles were deposited on multiwalled carbon nanotubes (MWCNTs) by adsorption of MoO2(acac)(2) and carburization in methane. Although the Mo2C/CNT electrodes studied herein worked at a much higher overvoltage compared to Pt-based electrodes, nevertheless, their activity thus proven may be further improved. Hence, the combination of Mo2C and CNT presented herein is a step on the way to develop Pt-free electrodes. (c) 2006 The Electrochemical Society.
