A cross-flow interconnect and a fuel cell stack including the same, the interconnect including fuel inlets and outlets that extend through the interconnect adjacent to opposing first and second peripheral edges of the interconnect; an air side; and an opposing fuel side. The air side includes an air flow field including air channels that extend in a first direction, from a third peripheral edge of the interconnect to an opposing fourth peripheral edge of the interconnect; and riser seal surfaces disposed on two opposing sides of the air flow field and in which the fuel inlets and outlets are formed. The fuel side includes a fuel flow field including fuel channels that extend in a second direction substantially perpendicular to the first direction, between the fuel inlets and outlets; and a perimeter seal surface surrounding the fuel flow field and the fuel inlets and outlets.

A method of preparation and application for a glass ceramic sealing thin strip with high sealing performance, differing from using conventional glass ceramic packaging paste applied to the junction of the cell stack assembly and connecting plates. The glass ceramic sealing thin strip of present invention utilizes tape casting to produce a single layer or multi-layer stacking in accordance with the required thickness of the glass-ceramic sealing thin strip, and cutting the glass ceramic sealing thin strips from molds in accordance with the geometry of cell stacks with equal thickness of the glass ceramic sealing thin strip for SOFC cell stack assembly, aiming to overcome the setbacks of the conventional dispensing method with glass ceramic packaging paste that makes the thickness difficult to control, and to effectively improve sealing performance of the cell stack assembly and the power generation efficiency, and achieve commercial application with mass production.
