Abstract:
1. A solid oxide fuel cell stack, comprising: a cell array in which M (where M is a natural number) interconnector unit solid oxide fuel cells are connected in parallel to form a bundle, and N (where N is a natural number) bundles are connected in series; a first current collecting member connected to a first bundle of the N bundles, the first current collecting member including a first terminal, and a second current collecting member connected to an N a first elastic insulating member adjacent to the first current collecting member, the first insulating member having a first opening at a portion away from its edges, a second elastic insulating member adjacent to the second current collecting member, the second insulating member having another first opening, and the first terminal passes through the first opening and the second terminal through the other first opening, wherein each of the unit solid oxide fuel cells comprises a first electrode layer, an electrolyte layer, and a second electrode layer sequentially laminated from an inside of the solid oxide fuel cell, and an interconnector connected to the first electrode layer and exposed to an outside of the unit solid oxide fuel cell, the interconnector being insulated from the second electrode layer, and wherein the first current collecting member is in direct contact with the interconnectors of the unit solid oxide fuel cells of the first bundle of the N bundles.
