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.
