Abstract
A platinum (Pt)/ruthenium (Ru) alloy catalyst, highly resistant to CO poisoning, having a lattice constant of 3.856-3.885 Å and a particle size of 2-5 nm, and supported on a carrier. The Pt/Ru alloy catalyst is highly resistant to CO poisoning, thereby allowing for higher catalytic activity when used. That is, an electrode and a fuel cell having a longer lifetime can be prepared using a smaller amount of the Pt/Ru alloy catalyst.
