摘要：
In this study, the performance of an SOFC (solid oxide fuel cell) and an MCFC (molten carbonate fuel cell) combined system is analyzed. Because SOFCs cannot completely use their fuel, the remaining fuel must be handled effectively. In general, MCFCs can be run at the high operating temperatures required for SOFCs; therefore, the exhaust gas from an SOFC, which still contains useful fuel, can be directly fed into an MCFC. The effects of key operating conditions, such as temperature and fuel utilization, on the system performance are investigated. A simulation of this combined fuel cell system shows an electrical efficiency of 55.22%, which is higher than a single SOFC. The efficiency of the combined fuel cell system can be further improved by adjusting operating conditions. (C) 2016 Elsevier Ltd. All rights reserved.
