    Abstract: A solar power system and materials capable of storing heat energy by thermochemical energy storage are disclosed. Thermal energy is stored as chemical potential in these materials through a reversible reduction-oxidation reaction. Thermal energy from concentrated sunlight drives a highly endothermic reduction reaction that liberates lattice oxygen from the oxide to form O2 gas, leaving energy-rich, oxygen-depleted particles. When desired, the heat is recovered as the particles are re-oxidized in an exothermic reaction upon exposure to air. The system may be integrated with a power generation system to generate power.

    Abstract: An electrolyte membrane 22 constituting a membrane electrode assembly includes thick portions 23 having a relatively large thickness. The thick portions 23 have a strip shape and are disposed at a predetermined distance from each other along the electric conduction direction. The thick portions 23 extend from one side L1 of the electrolyte membrane 22 extending in a direction perpendicular to the electric conduction direction to the other side L2 of the electrolyte membrane 22 extending in the direction perpendicular to the electric conduction direction. The thick portions 23 have a convex shape with respect to the anode side surface and the cathode side surface of the electrolyte membrane 22.

  • Patent number: 9281529
    Abstract: A unitized electrode assembly (10; 110; 210; 310; 410) for a fuel cell includes, in addition to an anode catalyst layer (54; 254) and a cathode catalyst layer (56; 256), a polymer electrolyte membrane (52) having an acid functional group normally including H+ ions and an edge seal (66; 166; 266, 366, 466) containing alkali metal ions in a form, concentration, and/or location for delivery and dispersion into the membrane. The edge seal of the unitized electrode assembly is proximate, and typically contacts, the peripheral edge region (68) of the membrane in ion-transfer relation therewith, and alkali metal ions leach into the membrane during fuel cell operation to provide a desired ion exchange in the membrane.
