Resumo
Methane is the main constituent of natural gas and can be converted in energy with fuel cell application
and higher value-added chemicals cogeneration. In Alkaline Anion-Exchange Membrane Fuel Cell
(AAEMFC) is possible led in a way that leads to more oxidized products, therefore more electrons
transferred. The investigation was realized for the methane oxidation on Pt/C, Pd/C, Ni/C as catalysts.
The electrocatalysts were prepared using a sodium borohydride method with 20 wt% of metals loading
on carbon. The X-ray diffraction (XRD) analysis revealed a cubic face-centred structure (CFC) for Pt/C
and Pd/C catalysts, was observed Ni/NiO phases for Ni/C electrocatalyst. The Transmission Electron
Microscopy (TEM) exhibited a good dispersion of nanoparticles and some agglomerations on the
support, with a mean size of 6.4 nm for Pd/C, 5.7 nm for Ni/C and near to 2 nm size for Pt/C. The
experiments with AAEMFC showed that all materials can carry out the reaction spontaneously. Pt/C
catalyst presents energy density twice times higher than the other materials. FTIR data suggest that
methane was converted into small products organic molecules such as methanol and formate in
different potentials for Pt/C, Pd/C, and Ni/C.
