The present teachings are directed toward electrocatalyst compositions of
platinum, titanium and at least a third metal for use in fuel cells. The
electrocatalyst composition is composed essentially of platinum present
in an atomic percentage ranging between about 50 percent and about 85
percent, titanium present in an atomic percentage ranging between about 5
percent and about 30 percent, and at least a third 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 cobalt, ruthenium, rhodium, palladium, silver, osmium,
iridium and gold.
