  • POLYMER ELECTROLYTES AND DEVICES CONTAINING THEM
    Publication number: 20100273063
    Abstract: The application arises from studies that have shown that electrochemical cells containing SPEs including: (i) a non-volatile organic ionic salt; and (ii) an inorganic electrolyte salt have an improved conductivity across a range of temperatures, and are more stable to water compared to electrochemical cells containing SPEs including either an IL or an inorganic electrolyte salt.

  • Fuel-cell actuated mechanical device
    Publication number: 20070034523
    Abstract: A method generates mechanical energy by storing water in a fuel-cell and a pressure equalization device. The water stored in the fuel-cell is electrolyzed into hydrogen gas and oxygen gas, which displaces the water stored in the pressure equalization device. The displaced water is fed to a hydraulic device to drive the hydraulic device in a forward direction to produce mechanical energy.
