The objective of this study is to evaluate the performance of SOFC (Solid oxide fuel cell) installed in office buildings. The higher efficiency of power generation is considered advantageous for electricity oriented users like offices in commercial sector. Optimization model to minimize the system cost with co-generation was employed to analyze how SOFC could be competitive compared with conventional gas engine technology. The results suggest that SOFC is required to have the cost at most 1.3 times as large as gas engine co-generation even though SOFC is effective to reduce the primary energy consumption.
