  • Patent number: 8951312
    Abstract: A compact, chemical-mechanical apparatus, having no electrical components, for storing and generating hydrogen safely, on-demand, at the time and point of use in small or large quantities using the environmentally clean chemical reaction between sodium metal and water to generate hydrogen (H2) gas and sodium hydroxide (NaOH) byproduct is presented, for powering electricity generating fuel cells for large scale commercial and private electric motor vehicle transport. The apparatus of the present invention supports hydrogen gas generation by the controlled addition of liquid water to solid sodium metal to produce hydrogen gas and sodium hydroxide using only mechanical components without electrical components that require external power and can generate sparks or short circuits, producing catastrophic failure in hydrogen systems.

  • Publication number: 20150037246
    Abstract: Disclosed is a process for the production of hydrogen in a reactor system comprising a steam reforming reaction zone comprising a reforming catalyst and a membrane separation zone comprising a hydrogen-selective membrane. The process involves a reaction system of so-called open architecture, wherein the reforming zone and the membrane separation zone operate independently of each other. The invention provides the heat for the reforming reaction through heat exchange from liquid molten salts, preferably heated by solar energy.

  • Patent number: 8940061
    Abstract: An apparatus for generating hydrogen for fuel cells is provided. The apparatus includes a housing, a button, a first separating plate, a solid state reactant, and a separating membrane. The housing has an opening and a reservoir. The button connected to the housing covers the opening. The first separating plate disposed in the housing divides the reservoir into first and second sub-rooms. The opening communicates with the first sub-room and the first sub-room is suitable for storing a liquid reactant. The first separating plate has a through hole opposite to the button. The solid state reactant is disposed in the second sub-room. The separating membrane disposed on the through hole separates the first sub-room from the second sub-room. When the button is pushed, the button damages the separating membrane. Therefore, the liquid reactant flows to the second sub-room and reacts with the solid state reactant to generate hydrogen.

  • Patent number: 8927162
    Abstract: The present invention comprises fuel cells 84 disposed within a fuel cell module 2, a reformer 20, a reformer temperature sensor 148 for detecting a reforming state temperature, and a control section 110 for controlling the operation of the fuel cell module. The control section prohibits the normal startup POX and executes a restart control different from the normal startup POX when the reforming state temperature is at least in a high temperature region within the POX temperature band in a state in which the operation of the solid oxide fuel cell module is stopped.

  • Patent number: 8926942
    Abstract: Methods and systems for generating hydrogen and separating carbon dioxide from a feed stream including hydro-carbons and water are disclosed. In some embodiments, the method includes the following: providing a catalytic chamber including a monolithic structure having surfaces coated with carbon dioxide adsorbing materials and one or more washcoated layers of combined steam reforming, water gas shift, and combustion catalysts; directing the feed stream into said catalytic chamber; controlling the feed stream so that it has a temperature range that allows the reactive generation of carbon dioxide and hydrogen gas but does not cause substantial development of coke between hydrocarbons in the feed stream and said surfaces of said monolithic structure; and adsorbing said carbon dioxide generated by heating the feed stream, wherein said carbon dioxide is adsorbed onto carbon dioxide adsorbing materials on said surfaces of said monolithic structure.

  • Patent number: 8915979
    Abstract: The present application is directed to a gas-generating apparatus. Hydrogen is generated within the gas-generating apparatus and is transported to a fuel cell. The first fuel component is introduced into the second fuel component through a conduit which punctures a septum separating the reaction chamber and the first fuel component reservoir, and the fuel conduit introduces the first fuel component to different portions of the second fuel component to produce hydrogen.

  • Patent number: 8889098
    Abstract: A system and method of producing hydrogen from a mixture of hydrocarbon fuel and steam. Reaction cells are provided that each contains a first tube of hydrogen permeable material and a second tube of hydrogen impermeable material that are concentrically positioned. This creates a gap space between the first tube and the second tube. The gap space is heated by burning a combustion gas outside of the two concentric tubes. A water gas shift reaction occurs in the gap space. Hydrogen is created that permeates through the first tube and becomes separated from the remainder of the reaction gases. The hydrogen gas is collected for use. As such, the system and method acts both as a gas shift reactor and as a hydrogen separator even though it is a single unit.

  • Patent number: 8852822
    Abstract: When terminating power generation by a fuel cell 3 in a fuel cell system 1, an amount of a raw fuel material introduced to a reforming catalyst 2a of a reformer 2 is reduced. Here, before the temperature of the reforming catalyst 2a is lowered to the un-reformed gas generation temperature, an amount of water supplied to the reforming catalyst 2a is controlled to increase the temperature of the reforming catalyst 2a. Thus, upon termination of power generation in the fuel cell 3, no un-reformed gas is generated and the reformed gas is supplied to the fuel cell 3.
