This work presents the performance of the direct flame fuel cell based on the anode-supported solid-oxide fuel cell (SOFC) with a propane flame, which serves not only as a fuel reformer but also as a heat source to sustain the fuel cell operation. The anode-supported SOFC was successfully fabricated and showed an extraordinary fuel cell performance of 584 mW/cm2 by using a propane flame; far higher than that of the electrolyte-supported SOFC. The total flow rates of premixed propane-air greatly influenced the range of fuel cell operation and fuel cell performance. With the fixed flow rate of propane, the introduction of an air flow exhibited a complex effect on the peak power density and the maximum current density due to the variation of fuel cell temperature and fuel concentration.
