Artigo IPEN-doc 09467 Synthesis and characterization of PtRu/C catalysts by colloidal and deposition methods for fuel cell applications2003 - FRANCO, E.G.; OLIVEIRA NETO, A.; SPINACE, E.V.; LINARDI, M.; MARTZ, N.; MAZUREK, M.; FUESS, H.The Aim Of This Work Is To Compare The Catalysts Produced By The Bonnemann Method (Colloidal) And The Catalysts Produced By The Deposition Method. For Proton Exchange Membrane Fuel Cells Applications Both Methods Lead To A Good Electrochemical Behavior Of The Catalysts For The Oxidation Of Methanol. The Catalyst Structure Was Investigated By Transmission Electron Microscopy (TEM). Energy Dispersive Analyses (EDS) Were Used To Evaluate The Semi-Quantitative Composition Of The Catalysts And Electrochemical Behavior Was Analyzed By Cyclic Voltammetry (CV). Key words: Fuel Cell, Catalyst, Methanol, Electrocatalyst, Nanocrystal.
