20140278709 | Intelligent CCHP System - Co-generating energy sources are controlled using a control system that monitors local and remote data. The local and remote data allow for energy management both in the short and long term by comparing the cost of using the co-generating energy source with other available energy sources. Individual co-generating energy sources can have their data aggregated and combined with remote data to allow for predictions of gross demand for energy. The gross demand can be used by an energy utility to plan for future energy needs and to negotiate with energy providers based upon those needs. The energy utility may control the individual co-generating energy sources so as to most cost-effectively meet the needs of the user of the individual co-generating energy source. | 09-18-2014 |
20140272656 | Dynamically Responsive High Efficiency CCHP System - A highly efficient combined cooling, heating, and power (CCHP) system is capable of providing 100% utilization of an energy generator used by the system by distributing thermal and electrical outputs of the energy generator to loads and/or other storage apparatuses. The CCHP system includes an energy generator, which can be a fuel cell and a waste heat recovery unit that assists in recovering thermal energy from the energy generator and returning it to the energy generator, and/or providing it to a thermal load, or a storage as needed or desired. | 09-18-2014 |
20140272636 | Hybrid Autothermal Steam Reformer for Fuel Cell Systems - A reactant processing module with a hybrid autothermal reformer (HASR) can allow for control of both the amount of cathode recirculation and the amount of water sent to the HASR. At the beginning of life of the fuel cell, reactant processing module can operate on full cathode recirculation. As the fuel cell begins to age and become less efficient, the amount of nitrogen-heavy, vitiated air from the fuel cell cathode can be monitored by a control system and restricted using a valve. In order to compensate for the aforementioned restriction, the rate of input of the external air supply is increased to the HASR and the deficit in water is supplied in liquid form from a water reservoir and turned to steam within the HASR. The amount of liquid water input from the water reservoir that meets the need for continued efficient operation is relatively small. | 09-18-2014 |
20140268931 | POWER CONVERSION SYSTEM WITH A DC TO DC BOOST CONVERTER - A voltage booster allowing for increased utilization of low voltage, high current, unregulated DC power (“LVDC source”), such as, but not limited to, fuel cells, batteries, solar cells, wind turbines, and hydro-turbines. LVDC generation systems employing a variable low voltage DC-DC converter of the present disclosure may be used without a power inverter in applications requiring high voltage DC inputs and can also allow for the employment of common, low cost, reliable, low voltage energy storage chemistries (operating in the 12-48 VDC range) while continuing to employ the use of traditional inverters designed for high voltage power supplies. An embodiment of the DC boost converter includes a plurality of interleaved, isolated, full-bridge DC-DC converters arranged in a Delta-Wye configuration and a multi-leg bridge. | 09-18-2014 |
20140260964 | SYSTEM AND METHOD OF REGENERATING DESULFURIZATION BEDS IN A FUEL CELL SYSTEM - A desulfurization system is disclosed that facilitates in situ or ex situ regeneration of hydrocarbon desulfurization beds. The desulfurization system can use a bed characterization limit, a predetermined sulfur threshold or other metric to determine when the hydrocarbon desulfurization bed should be regenerated. The desulfurization system can include heat and air intakes and an air/sulfur purge outlet to allow for the removal of sulfur from the hydrocarbon desulfurization bed. Alternatively, the regeneration of hydrocarbon desulfurization bed may be performed in situ by a service technician by using a prebuilt appliance that is connected to the inlet and outlets of the desulfurization appliance. The prebuilt appliance heats and purges hydrocarbon desulfurization bed, in substantially the same manner as described just above, and captures the sulfur outside of the desulfurization system. | 09-18-2014 |
