Abstract:

Disclosed herein are a system and a method for the production of hydrogen. The system advantageously combines an independent high temperature heat source with a solid oxide electrolyzer cell and a heat exchanger. The heat exchanger is used to extract heat from the molecular components such as hydrogen derived from the electrolysis. A portion of the hydrogen generated in the solid oxide electrolyzer cell is recombined with steam and recycled to the solid oxide electrolyzer cell. The oxygen generated on the anode side is swept with compressed air and used to drive a gas turbine that is in operative communication with a generator. Electricity generated by the generator is used to drive the electrolysis in the solid oxide electrolyzer cell.

Abstract:

Disclosed herein are a system and a method for the production of hydrogen. The system advantageously combines an independent high temperature heat source with a solid oxide electrolyzer cell and a heat exchanger located between the cathode inlet and the cathode outlet. The heat exchanger is used to extract heat from the molecular components such as hydrogen derived from the electrolysis. A portion of the hydrogen generated in the solid oxide electrolyzer cell is recombined with steam and recycled to the solid oxide electrolyzer cell. The oxygen generated on the anode side is swept with compressed air and used to drive a gas turbine that is in operative communication with a generator.

Abstract:

Articles having surfaces with enhanced wetting properties are presented. One embodiment is an article having a surface configured for promoting a phase transformation from a liquid phase to a vapor phase. The article comprises an element comprising a surface disposed to be in contact with a liquid to be transformed to a vapor, and the surface comprises a plurality of surface features having a median feature size, a, and a median feature spacing, b, such that the ratio b/a is up to about 8. The surface comprises a material disposed to contact the liquid, and this material has a nominal wettability sufficient to generate a nominal contact angle of up to about 80 degrees with a drop of the liquid. Another embodiment is a fuel rod for a nuclear reactor comprising a surface configured as described above.

US Classification:

205789, 204412

Abstract:

An oxide-ion sensor includes an oxygen electrode, a sense electrode and a saturated (reference) electrode. The sense electrode is operated at a substantially constant current for determining an instantaneous value of a dissolved oxide-ion concentration in the molten salt electrolyte. The saturated electrode is used to determine a reference value of the dissolved oxide-ion concentration in the molten salt electrolyte. A dissolved oxide-ion concentration in the molten salt electrolyte is continuously monitored in-situ during the molten-salt based electrochemical reduction process by determining an equilibrium potential between the sense electrode and the saturated electrode with the sense electrode carrying a small current in a circuit that is completed using the oxygen electrode. In another embodiment, the dissolved oxide-ion concentration in the molten salt electrolyte is continuously monitored in-situ by determining an electrochemical impedance of the molten salt electrolyte using a pair of bare current-carrying conductors and a frequency response analyzer.

International Classification:

F02C 6/00

US Classification:

60 39182

Abstract:

A combined cycle power plant includes a gas turbine, a condensing stage, a steam turbine, and a heat recovery steam generator (HRSG). The HRSG is configured to generate steam for driving the steam turbine in response to heat transferred from exhaust gas received from the gas turbine at a first temperature and to transmit the exhaust gas to the condensing turbine at a second temperature that is lower than the first temperature.
