Abstract

Corrosivities and catalytic activities of platinum-transition metal alloy catalyses loaded on carbon substrate and were studied by electrochemical method using a unit cell. And the analysis of Pt-alloy catalyst was conducted by x-ray diffractometer. Among the catalysts, the Pt-Mo/carbon, Pt-Fe-Co/carbon and Pt-Fe/carbon catalyst showed more excellent cathodic current densities than others. It was found that most of cathodic current density for the Pt-Mo/carbon electrode was $120mA/cm^2$. The current density of the Pt-Fe-Co/carbon was much higher than that of Pt/carbon, reaching $200mA/cm^2$.
