Considerable effort has been devoted to de- persed aqueous phase. The aqueous phases in the two- velop electrocatalyst of the nanoscale metallic alloy microemulsion systems have the same volume fraction for the methanol fuel cells. The Pt-Ru binary metal- but with different composition (typical atomic compo- lic catalyst has been accepted as the best electrocata- sition: Pt:Ru:Mo = 4.5:4.5:1) as indicated in Table I. lyst for methanol oxidation in direct methanol fuel cells The two stable microemulsions were then mixed with (DMFC).
