  • Patent number: 8647762
    Abstract: A battery cell module includes an enclosure having an electrically non-conductive perimeter and at least one cover formed from a thermally conductive material. The cover has a substantially flat inner surface and sealingly engages the electrically non-conductive perimeter. A plurality of series-interconnected battery cells are placed together into facing contact with each other, an exterior one of the battery cells in facing contact with the inner surface of the cover to facilitate heat transfer therethrough and to provide a desired compression against the series-interconnected battery cells. A first end of the series-interconnected battery cells includes a positive terminal end, and a second end of the series-interconnected battery cells including a negative terminal end, the series-interconnected battery cells the positive and negative terminal ends extending through the electrically non-conductive perimeter.

  • Patent number: 8614029
    Abstract: The plant with high temperature fuel cells includes a multi component sleeve for a cell stack. Axially directed chambers for an afterburning process are arranged between the periphery of the stack and an outer region of the sleeve. A construction which fixes the chambers includes a corset-like cage, the cross-section of which perpendicular to the stack axis has essentially the shape of a regular polygon. An afterburning chamber is associated with each corner of this polygon. Radial spring forces respectively act from the corners onto the associated chamber and thereby press sealing edges of the chamber onto sealing strips between chamber and stack. The sealing edges form a closed edge of a trough-like space. The trough-like space is connected via a narrow passage with an axial collection passage for exhaust gas. This collecting passage is arranged between the trough-like space and the corner.

  • Patent number: 8603694
    Abstract: According to the invention, a fuel cell is operated at a working temperature of between 60° C. and 110° C. and thermally insulated from the exterior, the waste air from the cathode being cooled by a surplus of incoming air that is provided for the reaction. The supplied fuel is pre-heated during the exchange of heat. The fuel cell that is operated according to said method can be used in systems that are restricted by exposure to thermal stress and can be produced in a cost-effective manner.

  • Patent number: 8563187
    Abstract: The subject of the present invention relates to a method and a protector for reducing degradation of fuel cell systems at transitions in operation, in particular at electrodes or catalysts in a combustion chamber of a stack of a PEM fuel cell system in startup and shutoff events of the fuel cell system. A switchable material delivery device is provided for varying a delivery of material to the fuel cell system, so that a transition from a first state of the fuel cell system to a second state of the fuel cell system can be initiated, such that a potential difference between different electrodes can be effected. At least one reducing mechanism is provided for reducing the potential difference between the different electrodes during the transition, in which the reducing mechanism includes at least one compensating device for an unequal gas distribution by reducing the proportions causing degradation, to reduce degradation.

  • Patent number: 8563183
    Abstract: An integrated dry gas fuel cell (IDG-FC) is provided. The IDG-FC includes at least one solid oxide fuel cell having an anode, a cathode and an electrolyte membrane disposed between the anode and the cathode. The IDG-FC further includes a conversion bed, where carbon dioxide gas is provided to the conversion bed to convert carbon monoxide gas from the carbon dioxide gas. Solid carbonaceous fuel is provided to the conversion bed to promote the gas conversion. The carbon monoxide is provided as fuel to the anode, and air is supplied to the cathode to provide oxygen for oxidation of the carbon monoxide at the anode to generate electric power. This new process does not require water, and supplies the oxygen required for the oxidation reaction through an ionically selective solid oxide electrolyte membrane.

  • Patent number: 8563185
    Abstract: The invention relates to a process for the production of hydrogen and carbon dioxide from a hydrocarbonaceous feedstock, comprising: a) supplying a gaseous hydrocarbonaceous feedstock and steam to a reaction zone comprising a steam reforming catalyst and catalytically reforming the hydrocarbonaceous feedstock to produce a reformed gas comprising hydrogen and carbon dioxide; b) supplying a molecular oxygen-comprising gas to the permeate side of a first hydrogen separation membrane; c) contacting a part of the hydrogen with a first hydrogen separation membrane, allowing the hydrogen to permeate through the first hydrogen separation membrane and combusting the hydrogen with the molecular oxygen at a permeate side of the first hydrogen separation membrane to produce all heat necessary for catalytic reforming the hydrocarbonaceous feedstock; d) contacting the remainder of the hydrogen with a second hydrogen separation membrane, which is separate from the first hydrogen separation membrane, and allowing the hydroge

  • Patent number: 8486577
    Abstract: In a fuel cell system of the invention, a hydrogen leakage detection process closes a shutoff valve, which shuts off a supply of hydrogen from a hydrogen supply unit into a hydrogen supply flow path, and opens a pressure regulator, which reduces a pressure of hydrogen in the hydrogen supply flow path, so as to keep the hydrogen supply flow path in a state with no pressure regulation and make the fuel cell system in a leakage detectable state. In this leakage detectable state, the hydrogen leakage detection process measures at least one of a pressure and a flow rate as a state quantity of hydrogen in the hydrogen supply flow path that feeds the supply of hydrogen to fuel cells. The hydrogen leakage detection process analyzes a detected behavior of the state quantity in the leakage detectable process and specifies the occurrence of a hydrogen leakage in the downstream of the hydrogen supply unit.
