Abstract
A solid oxide fuel cell stack may include repeating fuel cell units each having a planar fuel cell, an interconnect, a cathode contact layer disposed between sealing strips, and an anode contact layer disposed between sealing strips. The sealing strips have end extensions which overlap with corner extensions on the interconnect. The extensions stack to form vertical columns which enclose the external manifolds, along with a manifold plate.
