Thermal Stress Simulations of SOFC Membrane-Electrode Assembly
The compatibility of various electrolyte and electrode combinations has been assessed based on viewpoints of mechanics. The membrane-electrode assembly (MEA) was mainly comprised of traditional ceramic-metal materials as well as solid electrolytes. Variations of key variables such as size and coefficient of thermal expansion were incorporated into ABAQUS sensitivity analyses. Accordingly, general design rules in manufacturing solid oxide fuel cell (SOFC) were proposed, and these rules were beneficial to produce multilayer MEA in the future.
