Abstract

Solid oxide fuel cells (SOFCs) consisting of an 8 mol % Y-stabilized ZrO2 (YSZ) electrolyte, La0.8 Sr 0.2 MnO3 -YSZ (LSM-YSZ) cathode, and Ni-YSZ anode support were operated directly using isooctane. The electrical performance of SOFCs operating with 5.3 vol % C8 H18 in N2 was measured over a temperature range of 600- 775°C. Open-circuit voltages achieved slightly over 1 V. The maximum power densities attained were 0.10 and 0.24 W cm2 at 650 and 700°C, respectively. Mass spectroscopy analysis showed C8 H18 thermally decomposed largely into ethylene and methane, which suggested SOFC fuel reactions primarily, involved these gas species.
