Modeling of a 5Â kWe tubular solid oxide fuel cell based system operating on desulfurized JP-8 fuel for auxiliary and mobile power applications

► Modeling of JP-8 fuel reformer integrated with a tubular solid oxide fuel cell (SOFC) stack. ► Autothermal reformer (ATR) is characterized to obtain optimum performance. ► System does not require external energy and steam at steady state. ► System efficiencies of 39.5% and 32.6% observed at ATR temperatures of 700 °C and 850 °C, respectively. ► Optimum operating range suggested by conducting parametric analyses.
