A by-product elimination device used in a power generation system includes a fuel pack provided with a fuel charged portion having a power generation fluid fuel containing hydrogen, and a power generation module which detachably attached to the fuel pack, the module including a reforming portion which transforms the power generation fuel supplied from the charged portion into first gas containing hydrogen gas and carbon dioxide, and a fuel cell which generates an electrical energy by using the hydrogen gas. The device includes an absorbent charged portion which selectively absorbs carbon dioxide contained in the first gas and feeds second gas whose carbon dioxide concentration is lowered by the first gas to the fuel cell.

摘要:
A process for the production of hydrogen and electrical energy, with zero emission of pollutants, from ethanol which is produced from biomass, which is characterized by the partial oxidation/reforming of ethanol with water for hydrogen production which is subsequently fed to a fuel cell for production of electrical energy, more specifically where an aqueous solution of ethanol originating from fermentation of biomass is separated by distillation or any other technique so as to obtain approximately 40-70% by weight of ethanol, preferably 50-60%, this mixture, mixed with a suitable quantity of air in such a way so as the ratio of moles oxygen per mole ethanol to be between zero and 0.5, is fed to a reactor in which the reactions of partial oxidation and reforming of ethanol are taking place over a suitable catalyst, where in the same or a different reactor the shift reaction is taking place and, if necessary, the reaction of combustion of CO or its conversion to CH4, where the gaseous mixture from the exit of the reactors which contain hydrogen in mixture with carbon dioxide, nitrogen, methane or other gases in small quantities, is separated to the extent which is desirable for any kind of application.
摘要:
A fuel processor and integrated fuel cell including a monolithic three-dimensional multilayer ceramic carrier structure defining a fuel reformer and including an integrated fuel cell stack. The reformer includes a vaporization zone, a reaction zone including a catalyst, and an integrated heater. The integrated heater is thermally coupled to the reaction zone. The fuel processor further includes an inlet channel for liquid fuel and an outlet channel for hydrogen enriched gas. The fuel processor is formed utilizing multi-layer ceramic technology in which thin ceramic layers are assembled then sintered to provide miniature dimensions in which the encapsulated catalyst converts or reforms inlet fuel into a hydrogen enriched gas.

The invention is an operating system for a fuel cell power plant that includes at least one fuel cell for producing electrical energy from a reducing and oxidant fluid and fuel processing components including a reformer and a burner for processing a hydrocarbon fuel into the reducing fluid, and a direct mass and heat transfer device secured in fluid communication with both a process oxidant stream and a plant exhaust passage, so that the device directly transfers mass such as water exiting the plant in a plant exhaust stream back into the plant within the process oxidant stream. The invention also includes a split oxidant passage that directs the process oxidant stream through the fuel cell and a reformer feed portion of the process oxidant stream into fluid communication with the fuel processing components. The system may also include an anode exhaust passage that directs an anode exhaust from the fuel cell into the burner, then directs the oxidized anode exhaust stream from the burner in heat exchange relationship with the reformer feed portion.
摘要:
A fuel cell assembly in which fuel cells adapted to internally reform fuel and fuel reformers for reforming fuel are arranged in a fuel cell stack. The fuel inlet ports of the fuel cells and the fuel inlet ports and reformed fuel outlet ports of the fuel reformers are arranged on one face of the fuel cell stack. A manifold sealing encloses this face of the stack and a reformer fuel delivery system is arranged entirely within the region between the manifold and the one face of the stack. The fuel reformer has a foil wrapping and a cover member forming with the foil wrapping an enclosed structure.

摘要:
The present invention provides a process for suppressing the formation of metal-containing coke during processing of a hydrocarbonaceous material, such as for example a hydrocarbon conversion processes. Electromagnetic radiation is applied to the hydrocarbonaceous material while heating the hydrocarbonaceous material to a temperature above 700 degrees F. The frequency of the electromagnetic radiation is preferably below 300 MHz. The process is particularly useful in the reforming of a hydrocarbon material for operation in a fuel cell.
摘要:
A process for performing energy conversion which comprises the steps of converting a fuel precursor containing hydrogen to produce substantial amounts of engine-fuel containing free hydrogen and utilizing substantial amounts of hydrogen in one or more devices selected from the group including a fuel cell, heat engine, and heat releasing combustor. Waste energy resources selected from the group including off-peak power, engine-cooling-system heat, exhaust-gas heat, and stopping energy, are utilized to produce engine-fuel from feedstocks selected from the group (of Equations 1-14) including fuel alcohols, phenols, ammonia, ammonium compounds, gasoline, diesel fuel, cyanoacetic acid, cyanocarbons, carbon, and water.
