Abstract: Interfacial thermal stress is a primary driver of delamination and mechanical degradation in solid oxide fuel cells (SOFCs). A three-dimensional multiphysics model is developed to quantify interfacial thermal stress across four critical interfaces: the anode support layer (ASL)/anode functional layer (AFL), AFL/electrolyte layer (EL), EL/cathode functional layer (CFL), and CFL/cathode current collector layer (CCCL). An orthogonal design method is employed, comprising 36 configurations generated by four factors – solid-phase volume ratios (VRs) of Ni/yttria-stabilized zirconia (YSZ) in the ASL and AFL, and lanthanum strontium manganite (LSM)/YSZ in the CFL and CCCL – each varied at six levels. The results show that considerable thermal stress can arise even under seemingly balanced compositions, with maximum interfacial stress exceeding 60 MPa. Among the four factors, the CFL composition exerts the strongest influence, followed by the AFL composition, while the ASL and CCCL show minimal effects. Temperature variation remains minor, confirming that stress evolution is governed predominantly by elastic mismatch rather than thermal gradients. The optimal configuration – VRs of 0.2 (ASL), 1.5 (AFL), 0.5 (CFL), and 2.0 (CCCL) – minimizes stress across all interfaces by enhancing mechanical compliance and interlayer grading. Conversely, the most unfavorable case (2.0, 2.0, 3.0, 0.8) yields the highest stress. [ABSTRACT FROM AUTHOR]
