  • Patent number: 11901596
    Abstract: The present disclosure relates generally to portable energy generation devices and methods. The devices are designed to covert formic acid into released hydrogen, alleviating the need for a hydrogen tank as a hydrogen source for fuel cell power. In particular, an electricity generation device for powering a battery comprising a formic acid reservoir containing a liquid consisting of formic acid; a reaction chamber capable of using a catalyst and heat to convert the formic acid to hydrogen and carbon dioxide; a fuel cell that generates electricity; a delivery system for moving converted hydrogen into the fuel cell; and a battery powered by electricity generated by the fuel cell is provided.
    Type: Grant

  • Patent number: 8974915
    Abstract: PU/ZnO nanocomposites are provided wherein the addition of less than 1 vol % 33 nm ZnO nanoparticles into a PU matrix effect a decrease in the Young's Modulus and storage modulus of the polymer, while simultaneously effecting an increase glass transition temperature of the polymer. Detailed experiments are described (e.g., FTIR, DMTA, FESEM and AFM) that suggest that the reaction between hydroxyl groups of the ZnO nanoparticles and isocyanate groups of the polyurethane prepolymer disrupts the self-assembly of the phase separation in PU. Phase separation is responsible for the good mechanical properties of PU. Further, detailed experiments suggest that the increase of the glass transition temperature results from the crosslinking effect of the ZnO nanoparticles.
