Title: Platinum nickel catalyst alloy

Abstract

A Pt--Ni catalyst is provided which demonstrates an unusually high oxygen reduction mass activity. In some embodiments, the Pt--Ni catalyst is a Pt--Ni binary alloy. In some embodiments, the catalyst may be characterized as having a Pt fcc lattice parameter of less than 3.71 Angstroms or 0.371 nm. In some embodiments the catalyst has a Pt fcc lattice parameter of between 3.69 Angstroms (or 0.369 nm) and 3.73 Angstroms (or 0.373 nm). In some embodiments, the catalyst may be characterized as having a composition of close to Pt.sub.xNi.sub.(1-x), where x is between 0.2 and 0.4. In some embodiments the catalyst comprises nanostructured elements comprising microstructured support whiskers bearing a thin film of nanoscopic catalyst particles comprising a catalyst material described above. The catalyst may be particularly useful as a fuel cell catalyst and more specifically as a fuel cell cathode catalyst.
