Abstract:
The present invention relates to an apparatus for manufacturing a flat-tubular electrode support and a manufacturing method thereof. According to the present invention, a flat-tubular tube has a flat upper side, a flat lower side, and multiple flow channels which penetrate the flat-tubular tube in the widthwise direction; the flat-tubular tube is mounted on a tube mounting space part of a tube processing frame member having a protrusion; and then the flow channels are closed by pressing a pressing part using a frame pressing apparatus to produce the flat-tubular electrode support. The pressing part presses both ends of the flat-tubular tube arranged in both ends of the tube mounting space part respectively. The apparatus for manufacturing a flat-tubular electrode support of the present invention includes a protrusion on the tube processing frame resulting in an effect of preventing occurrences of cracks on the tube during a drying process after press molding of the flat-tubular tube.
Abstract:
The present invention relates to a method for directly synthesizing carbon nanowires on the inner surface of a three-dimensional structure including a carbon structure, and more specifically, to a method for synthesizing carbon nanowires in pores of a structure or the surface of a gap with high density and a hierarchical structure thereof synthesized thereby. According to the present invention, fine pores or gaps inside a structure causing the degradation of mechanical properties and conductivity are filled carbon nanowires with high density, thereby improving the mechanical or electrical performance of final products.

Abstract:
PURPOSE: A flat tubular solid oxide cell stack minimizes the stress of cell stacking, minimizes a sealing region, lengthens a chemical reaction route, and minimizes the temperature change of gas and flux change. CONSTITUTION: A flat tubular solid oxide cell stack (100) is a plurality of unit cells which are laminated. The unit cell (110) is selected from a unit cell (110a) in which a connect hole (120) penetrating one side of a first gas flow channel is formed at both ends of the first gas flow channel; a unit cell (100b1) in which a connect hole penetrating two sides of the first gas flow channel is formed at one end of the first gas flow channel and a connect hole penetrating the upper side is formed on the other end of the first gas flow channel; a unit cell (100b2) in which a connect hole penetrating both sides is formed on one end of the first gas flow channel and a connect hole penetrating the lower part is formed on the other end of the first gas flow channel; and a unit cell in which a connect hole penetrating both sides is formed on both sides of the first gas flow channel.
