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:
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.
Abstract:
PURPOSE: A jig for a heat-treating flat tubular solid oxide cell stack is provided to increase a sealing effect by performing heat treatment while applying a predetermined pressure. CONSTITUTION: A jig for a heat-treating flat tubular solid oxide cell stack comprises a fixing unit (3), a contact pressurizing unit (1), and a vertical cell stack pressurizing unit (6). The fixing unit supports one side of a vertical stacked cell stack (4). The contact pressurizing unit supports the other side of the cell stack and applies a predetermined pressure. The weight pressurizing unit applies a predetermined pressure to the contact pressurizing unit. The vertical cell stack pressurizing unit applies a predetermined pressure to the top of the uppermost layer of the cell stack in a vertical direction. The weight pressurizing unit is slanted to the contact pressurizing unit such that the weight pressurizing unit is in contact with the contact pressurizing unit when it is viewed from the lateral side of the pressurizing units.
Abstract:
PURPOSE: A surface structure of solid oxide fuel cell is provided to prevent the increase of contact resistance, to obtain sufficient reaction area, and to uniformly distribute gas flow. CONSTITUTION: A surface structure of solid oxide fuel cell comprises: a plurality of hemisphere shaped engraved patterns(21) which is formed on one side of a plat or pipe type cell, and a plurality of channel shaped connect pattern(22) forming continuous channels by connecting the plurality of engraved patterns. The angle between the plurality of connecting patterns, which are connected to one of the engrave patterns, is 180° or more. The continuous channel formed by the engraved patterns and the connect patterns has a zigzag shape.
