Abstract :
Utilization of hydrocarbon fuels such as methane and bottled natural gas has been successfully demonstrated in the operation of high-temperature solid oxide electrolyte fuel cells. Previous experimental work is reviewed, and the operation of air tubular fuel cells containing yttria-stabilized-zirconia solid electrolyte at 1000°C and 250 mA/cm2 current density, maintaining fuel and oxidant utilizations of 85% and 25%, respectively, is reported. Stable cell voltages and hydrocarbon reformation profiles along the cell length were obtained during the cell tests
