Description

In recent years, promotion of stationary fuel cell cogeneration systems (FC-CGS) has been expanding in Japan for solving the global warming problem. Especially, the FC-CGS of a polymer electrolyte fuel cell or a solid oxide fuel cell was installed in the residential sector in Japan. Also, these systems are expected for the global warming protection in EU countries. Thus, in International Electrotechnical Commission/Technical Committee 105 (IEC / TC 105), the combined indexes in consideration of a Life Cycle Assessment (LCA) and/or its specification are developing in order to improve the quality of products. Since the contents of material for a device and/or the performance are attributed to the combined indexes, the integration of each factor for a communication is necessary to identify the characteristic of target one. In this study, the identification index was proposed on basis of a data envelope analysis (DEA), and defined as a FC-DEA. As a result, the efficiency values on basis of DEA (FC-DEA) were 0.846 of PEFC-CGS, 0.648 of SOFC-CGS (a planar type) and 1.000 of SOFC-CGS (an anode support type), respectively. It found that the FC-DEA would be identified on the difference of each specification of a device.
