Abstract :

Introduction: In the present work, iso-octane and steam are co-fed in a solid oxide reactor of the type Cu- CeO2/YSZ/Pt. The impact of temperature, feed composition and over potential on products� distribution and electro-catalytic activity is examined. Furthermore, the as prepared cell was also electrochemically characterized employing typical fuel cell measurements and AC impedance spectroscopy. Results & Discussion: Cu-CeO2 composites exhibited high (electro-) catalytic activity and stability. Fuel cell experiments showed that the achieved power densities were substantially increased with temperature and i-C8H18/H2O feed molar ratios. Conclusions: The obtained results show that i-C8H18 is efficiently reformed by H2O to syngas over Cu/CeO2 composites. Under open circuit conditions, the distribution of products is also influenced by the associated i-C8H18 thermal/catalytic decomposition reactions, while electro-oxidation of combustible species is prevailing during anodic polarization. Under fuel cell operation, the electrochemical performance of Cu-CeO2 was investigated by voltage-current density-power density and AC impedance measurements. The achieved power output was enhanced at higher cell temperatures and C/H2O ratios.
