摘要： The invention provides noble metal-free electro-catalyst compositions for use in acidic media, e.g., acidic electrolyte. The noble metal-free electro-catalyst compositions include non-noble metal absent of noble metal. The non-noble metal is non-noble metal oxide, and typically in the form of any configuration of a solid or hollow nano-material, e.g., nano-particles, a nanocrystalline thin film, nanorods, nanoshells, nanoflakes, nanotubes, nanoplates, nanospheres and nanowhiskers or combinations of myriad nanoscale architecture embodiments. Optionally, the noble metal-free electro-catalyst compositions include dopant, such as, but not limited to halogen. Acidic media includes oxygen reduction reaction (ORR) in proton exchange membrane (PEM) fuel cells, and direct methanol fuel cells and oxygen evolution reaction (OER) in PEM-based water electrolysis and metal air batteries, and hydrogen generation from solar energy and electricity-driven water splitting.

摘要： A hydrocarbon feed stream is exposed to heat in an absence of oxygen to the convert the hydrocarbon feed stream into a solids stream and a gas stream. The gas stream is separated into an exhaust gas stream and a first hydrogen 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. A solid carbon block is formed. Alumina is smelted using the solid carbon block to produce aluminum. At least a portion of the oxygen of the oxygen stream and a second portion of the carbon of the carbon stream are combined to generate power and a carbon dioxide stream. At least a portion of the aluminum and a third portion of the carbon of the carbon stream are combined and heated to produce aluminum carbide.

摘要： A vehicular power system, a vehicle and a method of providing auxiliary power to a vehicle using an auxiliary power unit that uses a molten metal anode solid oxide fuel cell rather than an internal combustion engine. The auxiliary power unit includes a container with numerous fuel cells disposed within it such that when the metal anode is heated, the metal converts to a molten state that can be electrochemically cycled between oxidized and reduced states by oxygen and a fuel present in the molten metal, respectively. The auxiliary power unit further includes a furnace that selectively provides heat to the fuel cells in order to place the anode into its molten metal state. Seals may provide fluid isolation between the molten metal within the container and the ambient environment.

摘要： A solid oxide fuel cell of the present invention includes: a fuel cell unit including a fuel electrode, a solid electrolyte and an air electrode layered in the written order; a current collection assisting layer that is layered on an air electrode side of the fuel cell unit; air channels disposed on the air electrode side; and fuel gas channels disposed on a fuel electrode side. The air channels and the fuel gas channels are defined and formed by a current collector on the current collection assisting layer and a current collector on the fuel electrode side of the fuel cell unit. The air channels and the fuel gas channels extend in the same direction that is perpendicular to the fuel cell unit layering direction. The current collector on the air electrode side is fixed to the current collection assisting layer at first fixing portions that extend in the air channel extending direction, and the current collector on the fuel electrode side is fixed to the fuel electrode side of the fuel cell unit at second fixing portions that extend in the fuel gas channel extending direction. The solid oxide fuel cell is characterized in that the current collection assisting layer has such flexural rigidity that is lower in a direction perpendicular to the air channel extending direction than in the air channel extending direction.

摘要： A SOFC system includes: a fuel cell stack; a reformer; an air supplier: a combustor; and a controller. In a stop control of the above system, the controller calculates an average of ratios of the air to the raw material supplied to the reformer as a first average, in a case in which a molar fraction of a hydrogen component in the anode off-gas is higher than a molar fraction of a raw material component in the anode off-gas, and calculates the average of the ratios of the air to the raw material supplied to the reformer as a second average, in a case in which the molar fraction of the hydrogen component in the anode off-gas is lower than the molar fraction of the raw material component in the anode off-gas. The controller controls the air supplier so that the first average is higher than the second average.

摘要： A high-temperature fuel cell system includes a reformer that reforms a hydrocarbon-based raw fuel to generate a reformed gas containing hydrogen, a fuel cell that generates power by using the reformed gas and an oxidant gas, and a burner that heats the reformer. The burner includes an anode-off-gas gathering portion that has an anode-off-gas ejection hole and at which an anode off-gas discharged from an anode of the fuel cell gathers. The anode-off-gas gathering portion surrounds a first cathode-off-gas passing area through which a cathode off-gas discharged from a cathode of the fuel cell passes. The anode-off-gas ejection hole is formed such that the anode off-gas ejected upward from the anode-off-gas ejection hole approaches the cathode off-gas passing upward through the first cathode-off-gas passing area. The anode off-gas ejected from the anode-off-gas ejection hole and the cathode off-gas that has passed through the first cathode-off-gas passing area are burned.
