Abstract

Disclosed is a solid oxide stack. The solid oxide stack according to the present invention includes: a module formed by stacking a plurality of unit cells; an upper manifold and a lower manifold installed to support a top surface and a bottom surface of the module, respectively; wherein each unit cell includes a cell frame with a central opening, an air electrode current collector, a solid oxide cell, and a fuel electrode current collector sequentially stacked and seated within the central opening, an interconnect formed on the cell frame having a fuel flow channel on one surface and an air flow channel on the opposite surface, a cell sealant positioned at the interface between the cell frame and the solid oxide cell, and a fuel electrode sealant positioned at the interface between the cell frame and the interconnect; and wherein the air flow channel opens to at least one side of the module. According to the present invention, the stack provides a removable modular unit structure without requiring an air electrode sealant, allowing defective or aged cells to be easily replaced without affecting the stack's overall performance. This simplifies maintenance, extends the stack's lifespan, and reduces operational costs.
