Creep Behavior of Porous Supports in Metal-support Solid Oxide Fuel Cells
Creep is the inelastic deformation of a material at high temperatures over long periods of time. It can be defined as timedependent deformation at absolute temperatures greater than one half the absolute melting. Creep resistance is a key parameter for high temperature steel components, e.g. SOFC metal supports, where high corrosion resistance is a major design requirement.
The four variables affecting creep rate are strain, time, temperature, and stress level and make creep difficult to quantify. In this work, the creep parameters of a SOFC metal support have been determined for the first time by means of a thermo mechanical analyzer (TMA) for stresses in the range of 1-17 MPa and temperatures between 650-750 °C.
The creep parameters of Crofer® 22 APU were also acquired and compared with values obtained from literature to validate the technique.
