Abstract
A novel and improved noble metal-chromium alloy catalyst is disclosed with catalytic oxygen reduction activity at least twice that of the unalloyed noble metal. The noble metal-chromium alloy catalyst disclosed has particular utility as an electrocatalyst for the reduction of oxygen which makes it particularly useful as a cathode catalyst in an acid fuel cell.
