Abstract

 The ability to perferentially tailor complex electrode assemblies via the deposition of colloidal suspensions consisting of catalyst, polymer, organic, and inorganic constituents dictates the efficiency and performance of PEM fuel cell membrane electrode assemblies (MEAs). In order to better understand the nano-scale composites we are constructing, it is necessary to evaluate the cross-sectional distribution of materials as well as the structure at the nanoscale utilizing TEM. Our proposal is to cross section several fabricated composites and determine the compositional variation and catalyst distribution within these composites.
