“PROCESS FOR PREPARATION OF ELETROCATALISADORES SAW CITRIC ACID CHEMICAL REDUCTION FOR APPLICATION IN CELLS THE FUEL WITH EXCHANGING MEMBRANE OF PRÓTONS”. The present invention mentions a process to it of preparation of dispersed metallic eletrocatalisadores of nanopartículas in carbon of high superficial area gotten by the acid reduction for citric. In this acid method the citric one functions as reducing agent you leave of them metallic. The eletrocatalisadores can be prepared from leave Pt, Ru, Pd, Rh, Mn, Faith, Co, To go, Me, Cr, V, W, Sn, U and land-rare or a combination of these. The thus gotten eletrocatalisadores can be applied as anode, in the oxidation of hydrogen, mixtures hidrogênio/CO and alcohol as directly combustible, and also as cathode, in the reduction of oxygen or air, in cells the fuels with exchanging membrane of prótons |
