Abstract Tubular solid oxide fuel cells (TSOFCs) generate high-grade waste heat during operation, but the existing recovery technologies designed for flat cannot be directly applied to TSOFC due geometry mismatch. To efficient harvest heat, a new geometry-matching hybrid system including and annular thermoelectric generator (ATEG) is synergistically integrated evaluate performance upper limit. A mathematical model formulated verified describe by considering various thermodynamic-electrochemical irreversible effects. Key indicators are established assess potential performance. Calculations show that peak power density corresponding efficiency of proposed enhanced 20.39 % 13.89 %, respectively, compared standalone TSOFC. Furthermore, exergy destruction rate reduced 7.04 %. Extensive sensitivity analyses indicate higher operating temperatures enhance system’s performance, while larger electrode tortuosity negatively affects it. Additionally, optimization paths ATEG explored improve considerations such as number thermocouples, leg radial width, thickness, or shape parameter. The three-objective yields an design solution entire system, offering valuable insights its operation.
