Abstract
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 55 percent and about 95 percent, titanium present in an atomic percentage ranging between about 1 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 copper, manganese and iron.
