Characterization of Proton Exchange Membrane Fuel Cell Cathode Catalysts Prepared by Alcohol-Reduction Process

Autor: Egberto Gomes Franco, Emília Satoshi Miyamaru Seo, Almir Oliveira Neto, Rubens Chiba, T. A. B. Santoro

Publikováno v: Materials Science Forum. :94-99

Pt/rare-earth cathode catalysts were synthesized by the alcohol-reduction process and its structure was investigated by transmission electron microscopy (TEM), energy dispersive analyses (EDS), X-ray Diffraction (XRD). The electrochemical behavior of

Synthesis and Characterization of Eletrocatalyst Powders for Application in PEM Fuel Cells

Autor: Nathalie Martz, E. Aricó, Marcelo Linardi, Egberto Gomes Franco, Christina Roth, Hartmut Fuess

Publikováno v: Materials Science Forum. :4-10

The Bonnemann method was chosen to synthesize carbon-supported Pt-Ru-Mo electrocatalyst powders, as this method leads to highly-dispersed nanoparticles with an average particle size of approximately 2 nm. Structural characterization of the resulting

Electro-oxidation of methanol and ethanol on Pt–Ru/C and Pt–Ru–Mo/C electrocatalysts prepared by Bönnemann's method

Autor: Ernesto R. Gonzalez, Marcelo Linardi, A. Oliveira Neto, Eliana Maria Aricó, Egberto Gomes Franco

Publikováno v: Journal of the European Ceramic Society. 23:2987-2992

Pt–Ru/C and Pt–Ru–Mo/C electrocatalysts prepared by Bonnemann's method have been studied as porous thin films on high surface area carbon electrodes, in order to evaluate their electroactivity on CO desorption in PEM fuel cells. Electrode precu

Ethanol Logistics for Fuel Cells Applications in Brazil

Autor: Egberto Gomes Franco, Carlos Eduardo Rollo Ribeiro, Flavio Taioli, Geraldo Francisco Burani, Paulo Lucas Dantas Filho

Publikováno v: ASME 2008 6th International Conference on Fuel Cell Science, Engineering and Technology.

One important element to reduce the impact of the present economic development model in nature is the energy generation. The need for more efficient sources of energy is evident, as the world relies on fossil fuel sources that become scarcer and expe
