Abstract: The invention provides solid oxide fuel cell devices and systems, each including an elongate substrate having an active end region for heating to an operating reaction temperature, and a non-active end region that remains at a low temperature below the operating reaction temperature when the active end region is heated. An electrolyte is disposed between anodes and cathodes in the active end region, and the anodes and cathodes each have an electrical pathway extending to an exterior surface in the non-active end region for electrical connection at low temperature. The system further includes the devices positioned with their active end regions in a hot zone chamber and their non-active end regions extending outside the chamber. A heat source is coupled to the chamber to heat the active end regions to the operating reaction temperature, and fuel and air supplies are coupled to the substrates in the non-active end regions.

Abstract: A fuel cell device is prepared by dispensing and drying electrode and ceramic pastes around two pluralities of removable physical structures to form electrode layers having constant width and a shape that conforms lengthwise to a curvature of the physical structures. An electrolyte ceramic layer is positioned between electrode layers, forming an active cell portion where anode is in opposing relation to cathode with electrolyte therebetween, and passive cell portions where ceramic is adjacent the active cell portion. The layers are laminated, the physical structures pulled out, and the lamination sintered to form an active cell with active passages in anodes and cathodes and passive support structure with passive passages in ceramic. End portions of at least one of the two pluralities of physical structures are curved away from the same end portion of the other of the two pluralities resulting in a split end in the fuel cell device.

Abstract: An active cell is prepared by dispensing first electrode sub-layers, pressing in physical structures to partially embed them in an uppermost sub-layer, and dispensing more first electrode sub-layers wherein dispensing is in order of increasing porosity, then drying the sub-layers to form a first electrode layer. An electrolyte layer is then formed thereon. Further preparation includes dispensing second electrode sub-layers over the electrolyte layer, pressing in physical structures to partially embed them in an uppermost sub-layer, and dispensing more second electrode sub-layers wherein dispensing is in order of decreasing porosity, then drying the sub-layers to form a second electrode layer. A laminated stack is formed, then the physical structures are pulled out. Sintering then forms the active cell with active passages embedded in and supported by the sintered electrode layers, and with decreasing porosity in the electrode layers in a thickness direction away from the electrolyte layer.

Abstract: A single monolithic ceramic substrate has rectangular dimensions with thermal expansion dominant along the length. An inactive ceramic portion substantially surrounds a fuel cell active portion of scalable power. The active portion comprises a plurality of three-layer active structures, each including an electrolyte disposed between a first polarity electrode and a second polarity electrode, the electrolyte layers being co-fired with the inactive ceramic portion, and a first or second gas passage respectively associated with each first and second polarity electrode. The plurality of active structures are stacked in the thickness dimension with alternating polarity such that first polarity electrodes of adjacent active structures face each other with the associated first gas passage shared therebetween and second polarity electrodes of adjacent active structures face each other with the associated second gas passage shared therebetween. The power is scalable according to the number of active structures stacked to define the plurality.
