| Summary: | The present invention relates to water- and ion-conducting membranes used for fuel cells, for heat and moisture exchange in heating/ventilation/air conditioning systems and for desalination.
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. |
