摘要:
The present teachings are directed toward electrocatalyst compositions of platinum, titanium, a third, fourth and possibly fifth metal for use in fuel cells. The electrocatalyst composition is composed essentially of platinum present in an atomic percentage ranging between about 30 percent and about 85 percent, titanium present in an atomic percentage ranging between about 5 percent and about 30 percent, a third metal present in an atomic percentage ranging between about 1 percent and about 30 percent, a fourth metal present in an atomic percentage ranging between about 1 percent and about 30 percent, and a possible fifth metal present in an atomic percentage ranging between about 1 percent and about 30 percent. The third metal can be at least one member selected from the group consisting of nickel, vanadium, molybdenum, copper, manganese, iron, cobalt, ruthenium, rhodium, palladium, silver, osmium, iridium and gold. The fourth and fifth metals are different from the third metal and each other and can be selected from the group consisting of scandium, vanadium, chromium, manganese, iron, nickel, copper, zinc, yttrium, zirconium, niobium, molybdenum, cadmium, tin, hafnium, tantalum and rhenium.
