Abstract

In this paper, we review our development activities of ultrathin film (UTF) PtNi and PtNilr oxygen reduction reaction electrocatalysts on 3M Nanostructured Thin Film supports. Significant improvements in electrocatalyst mass and specific activities have been achieved through optimization of electrocatalyst bulk and surface compositions and structures. The compositional and structural factors influencing catalyst activity were investigated by high resolution electron microscopy and x-ray adsorption spectroscopy, and modeled by density functional theory. Membrane electrode assemblies which incorporate UTF PtNi and PtNilr cathode catalysts have demonstrated performance and durability which approach or exceed several U.S. Department of Energy 2020 performance, durability, and platinum group metal content targets.
