Abstract: A non-catalytic microcombustion based FFC for the direct use of hydrocarbons for power generation. The potential for high FFC performance (450 mW·cm?2 power density and 50% fuel utilization) in propane/air microcombustion exhaust was demonstrated. The micro flow reactor was used as a fuel reformer for equivalence ratios from 1-5.5. Soot formation in the micro flow reactor was not observed at equivalence ratios from 1 to 5.5 and maximum wall temperatures ranging from 750 to 900° C. H2 and CO concentrations in the exhaust were found to have a strong temperature dependence that varies with the maximum wall temperature and the local flame temperature.

Abstract: A flame-assisted fuel cell gas turbine hybrid system including a first combustor, a second combustor, and a flame-assisted solid oxide fuel cell configured to receive syngas from the first combustor, react the syngas with oxygen ions to yield carbon dioxide and water, and provide unreacted syngas to the second combustor. The first combustor is configured to receive heated compressed air from an aircraft engine compressor and the second combustor is configured to provide heated air to an aircraft engine gas turbine to generate mechanical power.

Abstract: A high temperature heater lamp including a ceramic envelope is disclosed. The ceramic envelope is substantially infrared transparent and is composed of a refractory ceramic. The heater lamp also includes two lead wires communicatively coupled via a filament. The filament is enclosed within the ceramic envelope, which is evacuated. The heater lamp may include at least two metallic IR shields within the ceramic envelope, at least one located on either side of the filament. The filament may be tungsten, a carbon filament, or molybdenum. At least one end of the ceramic envelope may be sealed with a metal cap affixed to the ceramic envelope by a high vacuum sealant. The heater lamp may be configured to operate at above 1500° C. The ceramic envelope may have a wall thickness less than 1 mm thick.

Abstract: A thermochemical labyrinth reactor is disclosed. The reactor has a reoxidation zone and a reduction zone with electric heaters. A recuperation zone connects the reduction and reoxidation zones with first and second channels, the first channel adjoining the second channel, being separated by windows allowing an exchange of thermal radiation between channels while preventing gas exchange. The reactor also includes reactor plates composed of a reactive material, and a transit system running through the three zones, with the transit system configured to shuttle the plates between the reduction zone and the reoxidation zone, moving the plates along a circuit. The reactor also has a feedstock gas emitter to introduce a feedstock gas flowing opposite the movement of the plates. A gas extractor is configured to extract a product gas resulting from the feedstock gas being split by the oxidizing reactive material. All three zones are surrounded by an insulating housing.

Abstract: A micro-tubular flame assisted fuel cell (mT FFC) integrated with a rich-burn, quick-mix, lean-burn (RQL) combustor for reduced NOx. Fuel and oxidant pass into a first-stage, fuel-rich combustion chamber. The exhaust products pass to the fuel cell for electrochemical conversion. Any remaining fuel is quickly mixed in a jet of oxidant to reduce temperature gradients and NOx formation in a second stage, fuel-lean combustion chamber. Preheating of the fuel, and different oxidant streams, is possible via heat exchangers in the fuel-rich and fuel-lean combustion chambers.

Abstract: A dual chamber solid oxide fuel cell integrated into the exhaust stream of an internal combustion engine, in which engine exhaust gases are routed to the anode of a tubular solid oxide fuel cell (SOFC) and heated secondary air is supplied to the cathode of the SOFC. The secondary air supply is heated using the existing engine temperature and exhaust gas temperature through a heat exchanger formed by a modified cylinder head and exhaust manifold. The dual chamber solid oxide fuel provides the necessary hydrocarbon and carbon monoxide scrubbing to achieve mandatory catalytic conversion for vehicle operation. In addition, the dual chamber solid oxide fuel cell is capable of generating sufficient electrical power for the vehicle. Omission of conventional catalytic convertors and alternators allows for improved efficiency and fuel economy of the internal combustion engine.

Abstract: A porous solid oxide fuel cell (PSOFC) system for electricity and syngas co-generation. The system has a porous layer, a porous electrolyte layer with catalyst, a porous anode layer, and a porous catalyst layer. A fuel air/O2 mixture is introduced from through the porous cathode layer so that it next passes through the porous electrolyte layer with catalyst, then the porous anode layer, and finally the porous catalyst layer. Syngas exits the porous catalyst layer with electricity being produced across the anode and cathode layers.
