Characterization of a novel, highly integrated tubular solid oxide fuel cell system using high-fidelity simulation tools

► A novel, highly integrated tubular SOFC system is characterized. ► High-fidelity stack model captures thermofluidic interactions in/around the stack. ► Radiation dominates heat transfer from small scale (<1 kW) stacks. ► Cell power disparities are tied to wall temperatures surrounding the stack. ► Typical SOFC operating strategies are altered by the highly integrated system.
