Claim 0:
1. A fuel cell column, comprising:
a stack of alternating fuel cells and interconnects, wherein the interconnects separate adjacent fuel cells in the stack and contain fuel and air channels which are configured to provide respective fuel and air to the fuel cells;
a manifold plate comprising a bottom inlet hole and a bottom outlet hole located in a bottom surface of the manifold plate, top outlet holes and top inlet holes formed in opposing sides of a top surface of the manifold plate, outlet channels that extend inside of the manifold plate to fluidly connect the top inlet holes to the bottom inlet hole, and inlet channels that extend inside of the manifold plate to fluidly connect the top outlet holes to the bottom outlet hole; and
a mitigation structure configured to reduce stress applied to the stack due to at least one of a shape mismatch or coefficient of thermal expansion mismatch between the stack and the manifold plate.
