摘要： In an SOFC stack system, wherein a CPOx reformer supplies reformate to the stack, a portion of the anode tail gas is recycled directly into the anode inlet of the stack, such that the fuel reaching the anodes is a mixture of fresh reformate and recycled anode tail gas and is present at a sufficiently high temperature that endothermic reforming of residual hydrocarbons from the CPOx reformer occurs within the stack. Preferably, an amount of secondary non-reformed fuel is also added to optimize the fuel mixture presented for internal reforming. The anode tail gas is hot, at the stack temperature of 750-800° C., which allows for the mixture of anode tail gas and secondary fuel to be mixed and reacted in a clean-up catalyst to react higher hydrocarbons in the secondary fuel, without additional oxygen, prior to being mixed with reformate and sent to the stack.

The layered structure of the mixed conducting oxygen transport materials contains an intermediate porous layer of mixed conducting oxygen transport materials formed on the porous substrate with a dense impervious layer of mixed conducting oxygen transport materials over the intermediate porous layer, and an optional surface exchange layer of mixed conducting oxygen transport materials over the dense impervious layer. The layered structure and the reforming catalyst layer are formed in separate steps.

摘要： A method of operating an oxygen transport membrane based reforming system employing one or more packs of thermally coupled panels of reformer tubes and oxygen transport membrane (“OTM”) reactors close to thermo-neutral point is provided. The method produces syngas by converting a hydrocarbon-containing feed, such as natural gas in the reformer tubes of a pack by endothermic steam reforming reactions. The heat required for endothermic reforming reactions is provided by exothermic oxidizing reactions occurring inside the OTM reactors of the pack. At a thermo-neutral point the heat released by exothermic reactions matches the heat required to support endothermic reactions and heat losses in the pack. The method modulates the flow rate of hydrocarbon-containing feed and/or steam-to-carbon ratio of the combined feed to the pack to maintain the surface temperature of oxygen transport membrane reactors below a target maximum temperature. The syngas product oxygen-to-carbon ratio is maintained within a desired target range such that the OTM based reforming system is operated close to thermo-neutral point.

摘要： A housing rotatably supports a desiccant wheel, Ambient air passes through one part of the housing and hot exhaust air passes through the other part. As the wheel rotates, it absorbs moisture from the ambient air in part of the housing and desorbs moisture into the exhaust air in the other part. A fuel cell system supplies the hot exhaust air directly to the desiccant wheel, The dry ambient air is directed to an evaporative cooler and divided between dry channels and wet channels, The air passing through the dry channels cools to be directed to a conditioned space. The air passing through the wet channels evaporates water in the channels facilitating heat transfer and adding moisture to that air. The air from the wet channels is optionally added back into the air from the dry channels to provide appropriate humidity.

摘要： An SOFC stack system including a reformer and fuel flow arrangement permitting optimized fuel reforming at all power load levels between 0% and 100%. A portion of the anode tail gas is combined with fresh air and fuel. The mixture is sent to a main reformer configured for endothermic reforming. Reformate is sent through a hydrocarbon cracker that breaks any hydrocarbons in the reformate into methane before the reformate enters the stack. At 100% load, there is no reforming in the main reformer; all of the fuel is internally reformed within the stack. At 0% load, all of the fuel is reformed in the main reformer. At loads between 0% and 100%, reforming is a mixture of endothermic reforming in the main reformer and internal reforming of methane within the stack. This strategy allows highest fuel processing efficiencies available through the full range of stack operation.

摘要： A solid-oxide fuel cell system including an integrated reforming unit comprising a hydrocarbon fuel reformer; an integral tail gas and cathode air combustor and reformer heat exchanger; a fuel pre-heater and fuel injector cooler; a fuel injector and fuel/air mixer and vaporizer; a reforming air pre-heating heat exchanger; a reforming air temperature control valve and means; and a pre-reformer start-up combustor. The integration of a plate reformer, tail gas combustor, and combustor gas heat exchanger allows for efficient operation modes of the reformer, both endothermic and exothermic as desired. The combustor gas heat exchanger aids in temperature regulation of the reformer and reduces significant thermal gradients in the unit.
