Since 1990 FN S.p.A (a 98.65% ENEA participated Company), in collaboration with ENEA and AFCo-Ansaldo Fuel Cells Company, has been involved in research and development activities in the field of high temperature fuel cell porous components and in their traditional manufacturing processes (tape casting and sintering). In alternative to the traditional tape casting technology, FN has developed an innovative process based on the moulding plastic technology for the production of MCFC ceramic matrixes. With the new technology the environmental impact is reduced as it has been shown by LCA (Life Cycle Assessment) preliminary studies. These results are not the only advantages: the new process allows the realization of various and/or complex component shapes, a higher productivity level, cost reducing and the complete re-workability of rejects. In this paper a comparison between the traditional tape casting process and the new route process is shown. Copyright (C) 2011, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd.
