LOPEZ-ROSAS, D. M. et al. Synthesis of Pt-Ni/CNT Cathodic Catalyst and its Application in a PEM fuel Cell. J. Mex. Chem. Soc [online]. 2021, vol.65, n.1, pp.39-51.  Epub 04-Jun-2021. ISSN 1870-249X.  https://doi.org/10.29356/jmcs.v65i1.1268.

This work reports the synthesis, characterization, and catalytic activity of Pt-Ni/CNT with a low platinum load to use as cathode electrocatalyst in PEMFC (proton-exchange membrane fuel cells). The synthesis of nickel particles on the carbon nanotubes surface was carried out by chemical reduction of a Ni(ethylenediamine) complex; after that, the galvanic displacement reaction was performed to platinum deposition onto Ni/CNT. The Pt-Ni/CNT was deposited by spray technique on a gas diffuser layer (GDL) and subsequently subjected to several potential cycles to promote Ni atoms migration. Finally, its catalytic activity was evaluated in a fuel cell.

Palabras llave : Pt-Ni; PEMFC; potential cycles.
