  • Water- and ion-conducting membranes and uses thereof
    Patent number: 6413298
    Abstract: Water- and ion-conducting membranes composed of sulfonated statistical arylvinyl polymers, the arylvinyl polymer comprising at least one arylvinyl monomer and at least one olefin monomer and wherein aromatic moieties derived from the arylvinyl monomer are at least partially sulfonated, are used as proton-conducting membranes for production of electricity, as water-conducting membranes for humidification of fuel gases in fuel cells and heat and moisture exchange in heating/ventilation/air conditioning systems. Water-conducting membranes composed of sulfonated arylvinyl polymers, the arylvinyl polymer comprising at least one arylvinyl monomer and wherein aromatic moieties derived from the arylvinyl monomer are at least partially sulfonated are used for desalination of seawater.
    Type: Grant
    Filed: July 28, 2000
    Date of Patent: July 2, 2002
    Assignee: Dais-Analytic Corporation
    Inventors: Gary Edmund Wnek, Scott G. Ehrenberg

  • Ion-conducting membrane for fuel cell
    Patent number: 6110616
    Abstract: Ion-conducting membranes for fuel cells are disclosed. The membrane is composed of a hydrogenated and sulfonated statistical copolymer of styrene and butadiene. A preferred membrane is obtained by hydrogenating a copolymer of styrene and butadiene to obtain less than five percent residual unsaturation, then sulfonating the polymer with an acetyl sulfate sulfonation agent to a level of at least 30 mol % percent sulfonate.
