A method of making an interconnect for an electrochemical cell stack includes providing the interconnect, and creep flattening the interconnect prior to placing the interconnect into the electrochemical cell stack.

Methods and devices for preventing thermally-induced stress cracks in large footprint solid oxide fuel cell columns

Various embodiments include interconnects and/or end plates having features for reducing stress in a fuel cell stack. In embodiments, an interconnect/end plate may have a window seal area that is recessed relative to the flow field to indirectly reduce stress induced by an interface seal. Other features may include a thicker protective coating and/or larger uncoated area of an end plate, providing a recessed portion on an end plate for an interface seal, and/or recessing the fuel hole region of an interconnect relative to the flow field to reduce stress on the fuel cell. Further embodiments include providing intermittent seal support to minimize asymmetric seal loading and/or a non-circular seal configuration to reduce stress around the fuel hole of a fuel cell.
