Abstract: A solid oxide fuel cell system including electric resistance elements for heating of space and components within the "hot zone" enclosure of the system, preferably in combination with means for using "waste" heat from other sources, to assist in warm-up from a cold start and/or to maintain a stand-by temperature of reformer and fuel cell elements within the system and/or to maintain optimum operating temperatures within the system during periods of very low electrical demand on the system. A method is included for using off-peak grid electricity, battery-stored onboard electricity, or vehicle-generated electricity to energize the resistance heaters, as well as utilizing gaseous waste heat sources such as vehicle exhaust gas to complement the resistance heating.

Abstract: A system comprising a cylindrical housing containing a sorbent cartridge selective of one or more gases in a gaseous mixture. End caps on opposite ends of the housing seal to the ends of the cartridge and direct the flow of gas mixture through a portion of the cartridge. The first end cap has entrance and exit ports for the gas mixture and for a purging gas for cartridge regeneration. The second end cap includes a compartment to receive and return the gas mixture to the first cap exit port. The purging gas follows a similar pathway via the remaining portion of the cartridge. The cartridge is rotatable within the housing; thus, the exhausted portion of the medium may be rotated into position for regeneration while a regenerated portion of the medium is rotated into position for re-use, thus providing continuous adsorption from the gas mixture.

Abstract: An internal combustion engine is supplied with reformate from a hydrocarbon reformer at engine start-up and during engine warm-up. The reformate fuel mixture is fuel-lean at start-up to ensure that all the fuel is burned while the exhaust converter is thermally non-functional. Shortly after start-up, the mixture is changed to be fuel-rich, providing unburned reformate fuel in the exhaust stream. During start-up and warm-up, the output of an air pump is controllably divided between the reformer (primary air) and the engine exhaust system (secondary air). Unburned reformate from the engine and secondary air from the air pump ignite and thereby rapidly heat the converter. Gasoline or diesel fueling of the engine by fuel injection is preferably delayed until the engine and the converter both reach operating temperatures, whereupon the engine is fueled by fuel injection and further reforming is terminated.

Abstract: A method for improving the efficiency of a hydrocarbon catalytic reformer and close-coupled fuel cell system by recycling a percentage of the anode exhaust syngas directly into the reformer in a range between about 20% and about 60%. Oxygen is supplied to the reformer (12) at start-up. Under equilibrium conditions, oxygen required for reforming of hydrocarbon fuel is derived entirely from endothermic reforming of water and carbon dioxide in the recycled syngas. Recycling of anode syngas into the reformer increases fuel efficiency, adds excess water to the reformate to increase protection against anode coking, and protects the fuel cell stack (16) against air- and water-borne contaminants. A method for producing an excess amount of syngas for exporting for other purposes is also provided.

Abstract: Apparatus and method for operating a fuel cell system including a hydrocarbon catalytic reformer and close-coupled fuel cell stack by recycling anode syngas into the reformer in a range between 60% and 95% of the total syngas. At equilibrium conditions, oxygen required for reforming of hydrocarbon fuel is derived from endothermically reformed water and carbon dioxide in the syngas. Reforming temperature is between about 650°C to 750°C. The stack exit temperature is about 800°C to 880°C such that the required endotherm can be provided by the sensible heat of the recycled syngas. The stack has approximately equal anode and cathode gas flows in opposite directions, resulting in cooling from both the anodes and cathodes.

Abstract: A system for co-generation of electricity combining a hydrocarbon catalytic reformer, an SOFC assembly and a generator driven by a gas turbine. The fuel cell assembly recycles a high percentage of anode exhaust gas into the reformer. Oxygen for reforming is derived from water in an endothermic process. The stack exit temperature is normally above 800°C. DC power from the fuel cell assembly and AC power from the gas turbine generator are directed to a power conditioner. Anode exhaust gas including carbon monoxide and hydrogen is divided into a plurality of portions by which heat may be added to the reforming, gas turbine, and cathode air heating processes. Water may be recovered from the exhaust. A power system in accordance with the invention is capable of operating at a higher total efficiency than either the fuel cell component or the gas turbine component alone.
