Patent Number Title Of Patent Date Issued
8215864 Impact attenuator system July 10, 2012
An impact attenuator system includes a hyperelastic member that comprises an energy-absorbing material which behaves in a rate-independent hyperelastic manner so that its permanent set is minimized and the material can absorb tremendous amounts of impact energy while remaining fully
8129069 Fuel cell components including immobilized heteropolyacids March 6, 2012
A fuel cell component is made with a composite including a proton conducting polymer, a water insoluble proton conducting inorganic material, and a heteropolyacid immobilized by chemically bonding to the inorganic material. In another embodiment, the fuel cell component is made with
7897650 Ionically conductive polymers for use in fuel cells March 1, 2011
An ionically conductive polymer is a copolymer including first and second polymer segments. The first polymer segments have a hydrophobic character and a high oxygen permeability. The second polymer segments have a hydrophilic character and a low oxygen permeability. The copolymer has an
