The reforming chamber includes multiple electrodes positioned across from a ground plane inside a cylindrical support structure. An input tube receives and directs the mixture to the vertical cavity where the mixture rises past the electrodes. Mixture that is not broken down is recycled back to the bottom of the vertical cavity by a fan while the resultant hydrogen and carbon dioxide is allowed to rise to a trap that separates the hydrogen from the carbon dioxide. The hydrogen can then be directed to the fuel cells or other hydrogen-dependent devices. | 10-22-2015 |
20150318568 | High Specific Energy Aqueous Flow Battery - A discharge unit generates electric power and a discharge fluid by simultaneously transferring acidic protons from a reducer fluid at a negative electrode of an electrolyte-electrode assembly (EEA) to an oxidant fluid at a positive electrode of the EEA through an electrolyte, and simultaneously transferring electrons from the negative electrode to the positive electrode through an external electric circuit. A neutral oxidant fluid is stored on board and is supplied to the discharge unit without prior on-board acidification. A regeneration system converts the discharge fluid into an alkaline discharge fluid using a base, splits the alkaline discharge fluid into a reducer and an intermediate oxidant in a splitting-disproportionation reactor, and releases the reducer and a base, while producing an aqueous multi-electron oxidant (AMO) by disproportionating the intermediate oxidant with the base. The regenerated AMO and reducer are supplied to the discharge unit for power generation. | 11-05-2015 |

20160017800 | METHODS AND SYSTEMS FOR ENERGY CONVERSION AND GENERATION - The invention relates to methods and systems of converting electrical energy to chemical energy and optionally reconverting it to produce electricity as required. In preferred embodiments the source of electrical energy is at least partially from renewable source. The present invention allows for convenient energy conversion and generation without the atmospheric release of CO2. One method for producing methane comprises electrolysis of water to form hydrogen and oxygen, and using the hydrogen to hydrogenate carbon dioxide to form methane. It preferred to use the heat produced in the hydrogenation reaction to heat the water prior to electrolysis. The preferred electrical energy source for the electrolysis is a renewable energy source such as solar, wind, tidal, wave, hydro or geothermal energy. The method allows to store the energy gained at times of low demand in the form of methane which can be stored and used to generate more energy during times of high energy demand. A system comprising an electrolysis apparatus and a hydrogenation apparatus, and a pipeline for the transportation of two fluids, is also described. | 01-21-2016 |
20160087297 | COOLING SYSTEM FOR FUEL CELLS - A fuel cell assembly has a fuel cell with a membrane electrode assembly disposed between an anode fluid flow plate and a cathode fluid flow plate. The cathode flow plate defines a flow channel for conveying oxidant to the membrane electrode assembly. The flow channel has an inlet and an outlet. A plasma discharge fan is configured to generate air flow into said inlet. The plasma discharge fan may also be configured to generate ozone flow into the inlet, thereby enhancing electrochemical reaction at the cathode side of the membrane electrode assembly. A plurality of the fuel cells may be configured in a stack arrangement, whereby the inlets for the plurality of fuel cells in the stack form an air inlet face of the fuel cell stack. The plasma discharge fan may comprise a plate structure disposed over the stack air inlet face, being configured to deliver a generally uniform air flow into the stack air inlet face over substantially its entire area. | 03-24-2016 |
