ABSTRACT

The Micro-CHP (Combined Heat and Power) cogeneration by Solid Oxide Fuel Cell (SOFC) integrated with Indirect Internal Reforming operation (IIR-SOFC) fuelled by methane is the focal point in this study. First, the paper introduces the framework of SOFC and the methane reformer respectively, and proposes the design of integrating SOFC with Indirect Internal Reforming operation (IIR-SOFC). Then, the numerical analysis of the system input-output relationship is performed by MAT-LAB software. The result shows that the output power and the stack temperature increase with the rising load current. Both the increase of the air input and methane input could raise the output voltage and power, but decrease the stack temperature. What’s more, the output of the IIR-SOFC system is more sensitive to a change in the methane input than to a change in the air input, so it regulates the inlet flow rates to keep the temperature and the output at desired levels.
