  • Fuel cells incorporating magnetic composites having distinct flux properties
    Patent number: 5928804
    Abstract: Magnetic composites exhibit distinct flux properties due to gradient interfaces. Such composites can be used, for example, to improve fuel cells and batteries and to effect transport and separation of different chemical species, such as transition metal species (lanthanides and actinides). A variety of devices can be made utilizing the composites, including a separator, an electrode for channeling flux of magnetic species, an electrode for effecting electrolysis of magnetic species, a system for channeling electrolyte species, a system for separating particles with different magnetic susceptibilities, as well as improved fuel cells, batteries, and oxygen concentrators.
    Type: Grant

    Date of Patent: July 27, 1999
    Assignee: The University of Iowa Research Foundation
    Inventors: Johna Leddy, Sudath Amarasinghe, Flavio Tinoco
  • Composites formed using magnetizable material, a catalyst and an electron conductor
    Patent number: 5817221
    Abstract: Magnetic composites exhibit distinct flux properties due to gradient interfaces. The composites can be used to improve fuel cells and batteries and effect transport and separation of different species of materials, for example, transition metal species such as lanthanides and actinides. A variety of devices can be made utilizing the composites including a separator, an electrode for channeling flux of magnetic species, an electrode for effecting electrolysis of magnetic species, a system for channeling electrolyte species, a system for separating particles with different magnetic susceptibilities, improved fuel cells, batteries, and oxygen concentrators. Some composites can be used to make a separator for distinguishing between two species of materials and a flux switch to regulate the flow of a chemical species. Some composites can control chemical species transport and distribution. Other composites enable ambient pressure fuel cells having enhanced performance and reduced weight to be produced.
