Abstract: The present invention is a mobile-energy generating system capable of providing redundant direct current power. It comprises a reciprocating engine and generator having dual fuel capability, a fuel cell, commercial electrical power hookups, and capacitors used for bridging purposes. Back-up fuel for the engine and fuel for the fuel cells are stored in propane and hydrogen storage tanks, respectively.

Abstract: The present invention is a power system using a reformer/fuel cell arrangement as the primary source of DC power. The reformer is operated on either natural gas or propane. A backup source of power consumes hydrogen which is diffused from a solid medium. On an as-needed basis, the medium is reacted to release hydrogen gas which is consumed by a fuel cell to generate backup DC power. The system also includes Lithium-Metal-Polymer batteries which are used for both bridging and backup purposes.

Abstract: The present invention is a modular power system using a fuel cell as a back-up power supply. The system includes lithium-metal-polymer (LMP) batteries to bridge and also for backup power if necessary. The entire system is preassembled ready for use so that it is available to a new or expanding site upon delivery. The total number of modular units used can simply be aggregated to meet additional power demanded.

Abstract: A power system utilizes a fuel cell for DC output, which is inverted to power an air conditioner. The air conditioner is used for the purpose of cooling equipment in the facility in the event the primary source of AC power fails. The air conditioner is located so that it is devoted to one or more computing devices in the facility. The selected devices are ones which perform some critical function, e.g., emergency communications.

Abstract: A power system that serves as a source of dedicated back-up power for a cooling system is disclosed. The power system utilizes a plurality of fuel cells, which produce direct current (DC) power. A conversion device, such as an inverter, is used to convert the DC into alternating current (AC) for powering the cooling system. A transfer switch connects the AC power from the inverter to the cooling system. The position of the transfer switch determines the source of AC power for the cooling system.

Abstract: The present invention is an energy generating system which uses an advanced aqueous-electrolyte energy storage system in conjunction with a commercial available primary source of power and a backup fuel cell.

Abstract: Various embodiments of a fuel-control system and associated methods for regulating the administration of a fuel to a fuel consuming device are disclosed. In one aspect, the fuel consuming device is a gas turbine receiving fuel through a feeder conduit from first and second sources of gas. According to one method, natural gas fuel is delivered from said first and second sources into said surge tank via first and second conduits, each conduit having pressure-control valves and sensors. The natural gas is delivered to the turbine from the surge tank via a feeder conduit. Pressure measurements are taken by the sensors for the first and second conduits, which are sent to a controller. The controller is then used to manipulate the valves to supply the turbine with fuel.

Abstract: The present invention is a DC power system incorporated into a modular housing. The primary source of power is an electrical utility. Because the electrical utility provides alternating current, the module includes a rectifier which makes the conversion to DC. The module also includes an air turbine which is used as a backup source of power. Also included is an array of lithium-metal-polymer (LMP) batteries to bridge and also for backup power if necessary.

Abstract: The present invention is a back-up power supply of alternating current and direct current, with the alternating current being generated by an inverter from the direct current, which is produced by a fuel cell. The inverter is at least partially encompassed by a phase changing material having an elevated melting point such that the phase changing material absorbs heat generated by the inverter as well as in the surrounding air, thereby maintaining the inverter temperature within acceptable limits. As the phase changing material absorbs the heat, its temperature rises and melts. Upon cooling of the system, the phase change material re-solidifies.
