To expand their application to a large scale, their integration with gasification systems using coal or biomass as feedstock shows potential (Moosavian et al. They can also be integrated with another power-generation source, as well as water heating and cooling devices used in residential homes (Sadeghi et al.

They have an electrical efficiency of about 60% under normal operation and up to 90% when combining heat and power operation (Ud et al.

2013) The advantages of such cells include the fact that a variety of fuels and electrolyte materials can be used and they show high electrical efficiency, full utility of heat and quiet operation (Secanell et al. These results demonstrate the reliability of the multi-stack design and the prospect of this SOFC power-generation system for further enlarging its application in a MW th demonstration.Īs the demand for green energy with high efficiency and low carbon dioxide (CO 2) emissions has increased, solid oxide fuel cells (SOFCs) have become an attractive technology (Choudhury et al. After 500 h operation, the performances of the stack towers decreased only slightly under lower current and showed almost no change under high current. The performances of each stack tower were almost identical at both the initial stage and after long-term operation.

The test lasted for more than 500 h as the fuel utilization efficiency was larger than 83%. The maximum steady output power of the system was 5700 W using hydrogen and 5660 W using syngas and the maximum steady electrical efficiency was 61.24% while the fuel utilization efficiency was 89.25%. In this work, a test rig (of a 5 kW SOFC system, with syngas from industrial gasifiers as fuel) was fabricated and subjected to long-term tests under high fuel utilization to investigate its performance. Thus, for commercial application of IGFCs, it is important to design reliable multi-stacks for large systems that show long-term stability and practical fuel gas for application to industrial equipment. Integrated gasification fuel cells (IGFCs) in particular show potential for large-scale power generation to further increase system efficiency. As the demand for green energy with high efficiency and low carbon dioxide (CO 2) emissions has increased, solid oxide fuel cells (SOFCs) have been intensively developed in recent years.
