  • Hydrophilic side-chain polymer, electrolyte membranes
    Publication number: 20060035987
    Abstract: Exemplary methods for the characterization of proton dissociation and transport for hydrophilic components of hydrated Polymer Electrolyte Membranes (PEM's) is described. Disclosed features and specifications may be variously implemented, controlled, adapted or otherwise optionally modified to improve differential hydrophilicity of the sidechain of any ionomeric PEM material. A representative embodiment of the present invention generally provides for the amelioration of electro-osmotic drag of water by protons, for example, in Direct Methanol Fuel Cells.
    Type: Application
