Discussions concerning the reliability of Solid Oxide Fuel Cells (SOFCs) are generally focused on the stability of the power output. However, the structural reliability of SOFCs is equally important. The structural behavior of these systems depends on the mechanical integrity of its ceramic components at room temperature, as well as across the range of the operating conditions. Manufacturing of these components can introduce flaws that are detrimental to their strength. In addition, residual stresses that result from processing can contribute to the effective stress state. There is limited detailed information regarding the flaws within these components and their relative contribution to the thermo-mechanical reliability over the desired lifetime of the SOFC stack. This talk will present results of experimental evaluations on the strength distributions of dense Magnesia Magnesium Aluminate (MMA) substrates. The flaw distribution and its importance to the reliability of the MMA components in SOFCs will also be discussed.
