摘要: A catalyst layer for use in a fuel cell includes catalytic nanoparticles and a perfluorosulfonic acid (PFSA) ionomer. The catalytic nanoparticles have a palladium or palladium alloy core and an atomically thin layer of platinum on an outer surface of the palladium or palladium alloy core. The PFSA ionomer has an equivalent weight equal to or greater than about 830. A unitized electrode assembly is also described.
