    Abstract: Anisotropic hydrophobic/hydrophilic nanoporous membranes and methods of forming anisotropic hydrophobic/hydrophilic nanoporous membranes are disclosed. The method of forming the nanoporous membrane includes growing a nanoporous oxide film on a substrate. A nanoporous membrane having a top side and a bottom side can then be formed by partially separating the nanoporous oxide film from the substrate. A fluorocarbon film can be deposited on the top side of the nanoporous membrane by plasma polymerization. The disclosed anisotropic hydrophobic/hydrophilic nanoporous membranes can have extremely different hydrophobicity between the top side and the bottom side of the nanoporous membrane.

    Abstract: Methods for optimizing, designing, making, and assembling various component parts and layers to produce optimized MEAs. Optimization is generally achieved by producing multi-layered MEAs wherein characteristics such as catalyst composition and morphology, ionomer concentration, and hydrophobicity/hydophilicity are specifically tuned in each layer. The MEAs are optimized for use with a variety of catalysts including catalysts with specifically designed and controlled morphology, chemical speciation on the bulk, chemical speciation on the surface, and/or specific hydrophobic or hydrophilic or other characteristics. The catalyst can incorporate non-platinum group metal (non-PGM) and/or platinum group metal (PGM) materials.
