Abstract

A micro-tubular solid oxide fuel cell (SOFC) is directly combined with a fuel-rich methane flame in a simple, "no-chamber" setup. The flame serves as a fuel partial oxidation reformer and a quick starter for the SOFC in the system. Experiments were performed using an anode supported micro-tubular SOFC and a multi-element diffusion flame burner for various equivalence ratios and gas flow rates. The SOFC was directly heated up by the flame from room temperature to operating temperature in less than 120 s. The maximum power generated by the fuel cell reached 0.45 W at the equivalence ratio of 1.2. The cell was operated at a fixed voltage of 0.45 V for three thermal cycles in 18 hours without significant performance degradation when the equivalence ratio was 1.2.
