摘要:
A gasket for a molten carbonate fuel cell formed of an elongated porous member able to support electrolyte flow and which includes barrier means for retarding such flow.
摘要:
A pre-processing assembly and method for processing fuel feedstock containing oxygen and hydrocarbons having higher and lower hydrocarbon content for a fuel cell, wherein the pre-processing assembly has a deoxidizing bed for reducing oxygen in the fuel feedstock and a pre-reforming bed for reducing higher hydrocarbon content in the fuel feedstock and wherein the deoxidizing bed and the pre-reforming bed are disposed within a common reaction vessel such that the fuel feedstock first passes through the deoxidizing bed and thereafter through the pre-reforming bed. The pre-reforming assembly may further include a propane processor bed for processing propane and propylene in the fuel feedstock, where the propane processor bed is disposed within the common reaction vessel with the deoxidizing bed and the pre-reforming bed.
摘要:
A caulk is provided for use in a fuel cell system having an externally manifolded fuel cell stack, forming a gas seal between a manifold gasket and the stack face. The caulk is formed of a ceramic material and a binder formed into a paste.
摘要:
An assembly having fuel cell plate structure adapted for use in a fuel cell in which gas flow channels are arranged to carry process gas adjacent the active and wet seal areas of the fuel cell, the plate structure having one or more baffles arranged such that when the plate structure is in the fuel cell the baffles of the plate structure cause the process gas flowing adjacent the wet seal areas to be directed away from the wet seal areas and toward the active areas of the cell.
摘要:
A gasket for use in a fuel cell system having at least one externally manifolded fuel cell stack, for sealing the manifold edge and the stack face. In accordance with the present invention, the gasket accommodates differential movement between the stack and manifold by promoting slippage at interfaces between the gasket and the dielectric and between the gasket and the stack face.
摘要:
An assembly having a dielectric frame which utilizes a plurality of segments, each segment having opposing first and second surfaces and first and second ends portions. Each of the first and second end portions has an end surface and a cutout extending from the end surface of the end portion along the length of the segment and from the first surface to the second surface. The segments of the frame are arranged in abutting relationship with the first surfaces of the segments aligned and the second surfaces of said segments aligned and with the end surface of a first end portion of a segment abutting the end surface of the second end portion of the adjacent segment. In this way, the cutouts of the first and second end portions of abutting segments form a keyway and a key is situated in the keyway so as to hold the abutting segments together. In accordance with the invention, certain of the segments are provided with recesses in the first surfaces of the segments adjacent the cutouts. Preferably, the recesses are formed as slanting or inclined surfaces which slant or incline into the thickness of the segment and are adjacent to and end at the far end of the slot, i.e., the end of the slot farthest along length of the segment.
摘要:
An integrated power production system including a fossil fuel power plant for processing fossil based fuel such as coal or natural gas arranged in tandem with a carbonate fuel cell having an anode and a cathode section. The flue gas of the power plant serves exclusively as the inlet gas for the cathode section of the fuel cell. Anode exhaust gas leaving the anode section of the fuel cell is subjected to processing including sequestration of the carbon dioxide in the exhaust gas.
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:
A fuel cell system in which a methane producing gasifier supplies methane fuel to an internal reforming fuel cell and unspent hydrogen from the anode exhaust of the fuel cell is used by the gasifier in processing the feedstock being converted by the gasifier to the methane fuel.
摘要:
Purification of hydrogen is realized in an assembly comprising anode and cathode gas diffusion electrodes, an electrolyte situated between the electrodes, first and second gas passages adjacent the electrodes and means for applying a voltage across the electrodes.
