    摘要: A seal assembly for a solid oxide fuel cell stack, includes at least two fuel cell stack components having opposed surfaces and a seal member disposed between the surfaces, wherein the seal member is a compliant seal member that is mechanically compliant in both in-plane and out-of-plane directions relative to the surfaces. The seal member is advantageously formed of one or more substantially continuous fibers. Further, preferred materials for the seal member are provided which advantageously allow for a desired level of impermeability while preventing contamination of the fuel cell stack.

    摘要: There is a method for modeling the surface fatigue life of a mechanical component. The method has the following steps: a) modeling the surface fatigue life of the mechanical component on an atomistic scale to form an atomistic model, b) modeling the surface fatigue life of the mechanical component on a mesoscale to form a mesoscale model, c) modeling the surface fatigue life of the mechanical component on a macroscale to form a macroscale model, and d) testing the surface fatigue life of the mechanical component. Feedback from the macroscale model is employed at least once to validate the atomistic model. Feedback from the macroscale model is employed at least once to validate the mesoscale model. Feedback from the testing is employed at least once to validate the macroscale model. There is also an interactive, multiscale model for prediction surface fatigue life or degradation rate for a mechanical component.
