摘要： Described herein are solid oxide fuel cells (SOFCs), comprising anode-conductor seals and/or cathode-conductor seals used for sealing porous metal structures and controlling the distribution of fuel and oxidants within these porous structures. For example, a SOFC comprises an anode conductor, cathode conductor, and electrolyte, disposed between the anode and cathode conductors. The anode conductor comprises multiple porous portions (permeable to the fuel) and a non-porous portion. The SOFC also comprises an anode-conductor seal, forming a stack with the non-porous portion. This sealing stack extends between the electrolyte and current collector and separates two porous portions thereby preventing the fuel and oxidant migration between these portions. In some examples, the sealing stack forms an enclosed boundary around one porous portion of the anode conductor. In the same or other examples, another sealing stack is formed in the cathode conductor, e.g., surrounding a fuel port extending through the cathode conductor.

摘要： A solid oxide cell device is provided which uses hydrocarbon fuel gas and oxygen to remove carbon dioxide from a gas stream, converting it to syngas (carbon monoxide and hydrogen), preferably without any input of external energy beyond that derived from the input gases. Existing processes can then be used to convert the syngas to stable liquid or solid organic chemicals, so that all the input carbon is fixed. Partial oxidation of hydrocarbon fuel gas in a solid oxide fuel cell produces syngas and electricity, and the electricity powers a solid oxide electrolyser which reacts carbon dioxide with further hydrocarbon fuel gas to produce more syngas. The fuel cell and electrolyser together can achieve self-sustaining carbon dioxide utilization.

摘要： The present invention relates to a composite of a cobalt-based perovskite material with a negative thermal expansion material, and a preparation method of the same, and a solid oxide fuel cell (SOFC) comprising the same, and belongs to the technical field of fuel cells. In the present invention, a negative thermal expansion material is introduced into a cobalt-based perovskite oxide to successfully prepare an SOFC cathode material with excellent electrochemical performance and low thermal expansivity. The composite electrode achieves prominent mechanical tolerance in SOFC, which can moderate a volume change during the whole calcination process and enable a smooth transition to a high-temperature stage. The composite electrode has a thermal expansion coefficient (TEC) only of 12.9×10−6 K−1, which is perfectly matched with that of an SDC electrolyte. In addition, the composite shows excellent oxygen reduction reaction (ORR) activity, high TEC, and extremely-excellent anti-CO2 poisoning performance.

摘要： A hydrocarbon feed stream is exposed to heat in an absence of oxygen (pyrolysis) to convert the hydrocarbon feed stream into a solids stream and a gas stream. The solids stream includes carbon. The gas stream includes hydrogen. The gas stream is separated into an exhaust gas stream and a first hydrogen stream. The first hydrogen stream includes at least a portion of the hydrogen from the gas stream. The carbon is separated from the solids stream to produce a carbon stream. Electrolysis is performed on a water stream to produce an oxygen stream and a second hydrogen stream. At least a portion of the oxygen of the oxygen stream and at least a portion of the carbon of the carbon stream are combined to generate power and a carbon dioxide stream. At least a portion of the generated power is used to perform the electrolysis on the water stream.
