  • Publication number: 20130252134
    Abstract: This invention relates to solid polymer electrolyte materials for use in one or more electrode of a fuel cell. The solid polymer electrolyte materials comprise one or more ionomer which comprises polymerized units of monomers A and monomers B, wherein monomers A are perfluoro dioxole or perfluoro dioxolane monomers, and the monomers B are functionalized perfluoro olefins having fluoroalkyl sulfonyl, fluoroalkyl sulfonate or fluoroalkyl sulfonic acid pendant groups, CF2?CF(O)[CF2]nSO2X. The ionomer of the solid polymer electrolyte material has a number average molecular weight, Mn, of greater than 140,000. Specifically, the ionomers of the invention may find use in the catalyst layer of an electrode because the high molecular weight ionomers mitigate the formation of cracks in the catalyst layer.

  • Patent number: 8332378
    Abstract: The system enables a data processing framework that polls for files using a listener, controls the workflow using event driven logic, processes financial transactions, and creates a business to business trading partner network. The listener ensures the reliability and data integrity of input files and performs archiving functions. The payment management functions automatically processes transactions, including payor (e.g., the buyer) initiated payments to a payee (e.g., a supplier) by utilizing a flexible, decoupled processing architecture. A payment management computer identifies a universal identifier for each entity and forms relationships and hierarchies in order to increase efficiency of the trading partner network. Metadata describes the format, validation and relationships for a wide variety of financial account data.
