The objective of this study is to evaluate the performance of SOFC (Solid oxide fuel cell) installed in office or hospital buildings. The higher efficiency of power generation is considered advantageous for electricity oriented users 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 system for large, medium and small scale buildings. The results suggest that SOFC is not expected competitive for office buildings while it can be feasible for hospitals for any building scale. The results also imply that the cost of SOFC needs to be reduced down to 500k¥/kW. Although SOFC is highly efficient in terms of power generation, utilizing co-generated heat is essentially important even for SOFC systems.
