Abstract
A fuel cell stack is described. The fuel cell stack comprises an interconnect assembly comprising a cathode-side interface coupled to an interconnect via a first joint, and an anode-side interface coupled to the interconnect via a second joint, the interconnect assembly having a first coefficient of thermal expansion (CTE) at an interface side of the interconnect assembly. The fuel cell stack further comprises a fuel cell element coupled to the interconnect assembly at the interface side via a hermetic seal, the fuel cell element having a second CTE at the interface side, the first CTE and the second CTE satisfying a predetermined CTE matching condition.
