Abstract
Various embodiments include interconnects for a fuel cell stack that includes a first support frame having a first surface that is configured to be secured to a first surface of a fuel cell. A gas flow separator section is secured to a second surface of the first support frame, opposite the first surface of the first support frame. A second support frame is secured to a second surface of a second fuel cell, opposite the first surface of the first fuel cell. The first and second support frames have a coefficient of thermal expansion (CTE) that substantially matches the CTE of the electrolyte material of the fuel cells, and the gas flow separator section has a CTE that does not substantially match a CTE of an electrolyte material of the fuel cells.
