A semi-internally manifolded interconnect structured for placement between successive electrolyte elements in stack of elements having a first surface with a level margin extending substantially around the perimeter of the interconnect, first and second manifold channels disposed inward from the margin, and a plurality of gas-flow channels disposed in a central area of the first surface and extending between and in fluid communication with the first and second manifold channels.
摘要:
An apparatus and method for enhancing the yield and purity of hydrogen when reforming hydrocarbons is disclosed in one embodiment of the invention as including receiving a hydrocarbon feedstock fuel (e.g., methane, vaporized methanol, natural gas, vaporized diesel, etc.) and steam at a reaction zone and reacting the hydrocarbon feedstock fuel and steam in the presence of a catalyst to produce hydrogen gas. The hydrogen gas is selectively removed from the reaction zone while the reaction is occurring by selectively diffusing the hydrogen gas through a porous ceramic membrane. The selective removal of hydrogen changes the equilibrium of the reaction and increases the amount of hydrogen that is extracted from the hydrocarbon feedstock fuel.
摘要:
The object is to rapidly clean-up an off-gas generated by blasting in a pressure vessel to such a level as to permit the exhaust of the off-gas. An object to be blasted is blasted in a pressure vessel to generate an off-gas, which is introduced into a combustion furnace to burning a combustible component contained in the off-gas. The off-gas after the burning in a reservoir section is stored in the reservoir section, and exhausted out of the reservoir section if a component contained in the off-gas complies a predetermined emission requirement, otherwise returned to at least one of the pressure vessel and the combustion furnace to be re-treated if the component does not comply the emission requirement.
摘要:
Syngas components hydrogen and carbon monoxide may be formed by the decomposition of carbon dioxide and water or steam by a solid-oxide electrolysis cell to form carbon monoxide and hydrogen, a portion of which may be reacted with carbon dioxide to form carbon monoxide. One or more of the components for the process, such as steam, energy, or electricity, may be provided using a nuclear power source.

摘要:
An improved ceramic interconnect component for a solid oxide fuel cell having good electrical conductivity and thermodynamic stability in the presence of fuel and a coefficient of thermal expansion matching closely that of zirconia electrolytes is disclosed. The interconnect is a lanthanum chromite material including strontium and magnesium as dopants.
摘要:
A fuel cell module (10) with a fuel cell column (18), having at least one fuel cell stack, mated with the planar wall of a heat exchanger (60), wherein the fuel cell column and heat exchanger are mounted to a support structure (30), and which define an air plenum between the fuel cell column and planar wall of the heat exchanger, thereby eliminating the ductwork and insulation requirements associated with heat exchange systems while increasing the efficiency of the heat exchanger.
摘要:
A thermally integrated heat exchange system for solid oxide electrolyte systems includes a thermally insulated furnace enclosure structure having an internal chamber therein and a plurality of solid oxide electrolyte plates disposed within the internal chamber. A heat exchanger particularly suited for use with the thermally integrated system has gas passageways for the flow of gases therethrough and is associated with the walls of the furnace enclosure. Thermal energy radiated from an operational solid oxide electrolyte system within the furnace enclosure may be used to preheat incoming reactant gases destined for use by the electrolyte plates. Exchange of thermal energy between hot exhaust gases and cooler incoming gases may also occur in the heat exchanger gas passageways that are substantially thermally integrated along their length.
摘要:
A modular arrangement for stacks of ion conducting electrolyte elements includes a plurality of solid state ion conducting electrolyte elements spaced apart and arranged into stacks and the stacks further arranged at regular intervals around a central plenum. A plurality of gas flow passageways are disposed in the spaces between the electrolyte elements to enable reactant gases to circulate between the elements. A pair of manifold plates are disposed on either side of the electrolyte elements and sandwich the elements therebetween.
