Enhancement of PEMFC performance by using carbon nanotubes supported PtCo alloy catalysts

Carbon nanotube-based PtCo (PtCo/CNT) alloy electrocatalysts for the oxygen reduction reaction were prepared by the silane-assisted deposition method. The transmission electron microscopy (TEM) reveals that the prepared PtCo alloy nanoparticles are uniformly dispersed on the surface of the CNTs support with narrow particle size distribution. As compared to Pt/CNTs catalyst, the bimetallic PtCo/CNTs catalyst exhibits an improved performance as cathode material in a H2/O2 fuel cell.
