ABSTRACT:
An anode-supported flat-tubular solid oxide fuel cell stack includes a plurality of fuel cells and a plurality of connector plates. Each of the fuel cells includes a supported tube having semi-cylinder parts and plate parts, a connector coated on an upper plate of the supported tube as a way to be positioned at the center of the upper plate, an electrolyte layer partly coated on an external surface of the supported tube except for a portion of the supported tube coming into contact with the connector, and an air electrode coated on an external surface of the electrolyte layer. Each of the connector plates includes a lower connector plate, middle connector plates, and an upper connector plate. A plurality of gas channels are formed on the middle and lower connector plates. The anode-supported flat-tubular solid oxide fuel cell stack has a large capacity, improved power density, and reduced production costs.
