    摘要： A thermally integrated fuel cell system includes a stack zone, a burner zone and a low temperature zone. The fuel is combined with steam and passed sequentially through a primary reformer and a secondary reformer or a radiative fuel heat exchanger. Air may be passed sequentially through an afterburner heat exchanger and a radiative air heat exchanger such that the radiative heat exchanger may be used to heat the stack zone. The stack exhaust is combusted in an afterburner. Afterburner exhaust heats the primary reformer, the high temperature air heat exchanger, the low temperature air heat exchanger and steam generator. The stack zone includes the stacks, the secondary reformer and the radiative heat exchanger. The burner zone includes the afterburner which includes a start burner, the primary reformer and the high temperature air heat exchanger. The low temperature zone includes the low temperature air heat exchanger and a steam generator.

    摘要： A biogas cleaning method for purifying a biogas waste stream to form a combustible clean biofuel uses a biogas cleaning system that includes a gas control system, a deoxidizer catalyst bed, a hydrosulfurization catalyst bed, a hydrogen sulfide adsorption bed and a thermal sensor controller. The biogas cleaning method includes using a biogas source to introduce a biogas waste stream into the biogas cleaning system, blending hydrogen with the biogas waste stream, combusting the blended hydrogen and biogas stream to remove oxygen, hydrogenating the heated biogas waste stream to convert sulfur species to hydrogen sulfide and adsorbing the hydrogen sulfide from the biogas stream. In some embodiments, a biogas cleaning system also includes a sulfur polisher adsorption bed, a chlorine removal adsorption bed, a siloxane removal adsorption bed, a heat exchanger loop and a biogas precooler. Some embodiments of a biogas cleaning method can also include precooling the biogas waste stream, adsorbing siloxanes from the biogas waste stream and adsorbing hydrogen chloride from the biogas stream.

    摘要： An electric power generation system incorporates one or more liquid feed fuel cells, and includes a removable and replaceable fuel cartridge module for storing, delivering and receiving a vaporizable liquid fuel such as aqueous formic acid. The system also includes a fuel delivery module, a fuel cell module, an exhaust module including a vapor cell for consuming unreacted vaporous fuel and a recycle liquid fuel stream, a moisture management module, and a power management module. In operation, a recycle liquid fuel stream is directed back to the fuel delivery module, and vaporous fuel in the fuel cell anode exhaust stream is converted in the vapor cell to substantially benign reaction products. The vapor cell exhaust stream is then directed through a filter in the fuel cartridge module, where residual vaporous fuel is trapped and a benign exhaust stream is discharged from the cartridge module.

    摘要： A passive-pumping liquid feed fuel cell system includes a cartridge module, a fuel delivery module, a fuel cell module and an exhaust module. In fuel delivery mode, a bladder in the cartridge module is passively pressurized by permeable gas separated from liquid fuel to a pressure greater than fuel cell pressure, and doses are delivered to the fuel cell by controlling a single fuel valve. In fuel return mode, unused liquid fuel is separated in the exhaust module while the fuel cell is operated in a temporary high load mode, thereby generating anode gas pressure greater than bladder pressure and transferring unused fuel back to the bladder. The returned fuel maintains bladder volume and internal pressure for ongoing fuel dosing. The system provides compact and efficient micro-dose operation of low power formic acid fuel cells, and is operable with highly concentrated stored fuel and resulting high energy capacity.

    摘要： A fuel cartridge stores and delivers a vaporizable liquid fuel stream to one or more fuel cells. The cartridge includes a housing with an interior cavity, a fuel stream port with a bidirectional flow valve, a pressure relief valve for discharging a gas stream at a set pressure, a bladder located within the interior cavity and formed from a liquid-impermeable and gas-permeable liner, and a compression mechanism for imparting positive pressure to the bladder. In a fuel storage mode, the compression mechanism induces flow of vaporous fuel through the bladder liner. When the fuel cell fuel stream inlet pressure is less than the bladder pressure, the bladder discharges a liquid fuel stream in a fuel delivery mode. When the fuel cell fuel stream inlet pressure is greater than the bladder pressure, the fuel cell outlet fuel stream is returned to the bladder in a fuel return mode.
