�p���v��In this research, a feasibility study is conducted into the evaluation items and evaluation methods that should be standardized for the micro-structures, mechanical properties and thermal properties of the single-unit or laminated ceramic materials that are used in solid oxide fuel cells (SOFC). The following describes the contents of this study.
(1) Implementation of an Investigation of Needs: In regards to the existing ISO and JIS standards, an investigation was conducted into the standards that could be applied to the evaluation of the characteristics of ceramic materials for SOFC. The following are the standards that were have the potential of being applied. For micro-structures, there were the sample preparation method for SEM observation and the grain size measuring method. For mechanical properties, there were the fracture toughness test, the Vickers hardness and the Weibull statistical analysis method for data. For thermal properties, there was the specific heat capacity measurement method. However, it was determined that the existing ISO and JIS standard are insufficient. On the other hand, we investigated the needs of the ceramic manufacturers who make SOFC materials and SOFC manufactures and asked how they were conduction performance evaluations of micro-structure, thermal and mechanical properties and what they were looking for. Based on this, it was determined that there is a need to evaluate the transmittance of electrodes for microstructures and the strength of thin sheet ceramics in the area of mechanical properties.
(2) Investigation into the Test Methods for Properties: In the area of the transmittance of electrodes, issues and mechanical properties, the ring-on-ring test and small punch were investigated as candidates for evaluating the strength of thin sheet ceramics. In addition, the test methods for both at room temperature and high temperature atmospheres and steps were taken and investigated for standardization.
(3) Investigation of Standardization: We visited experts in Europe and the current state of the evaluation of ceramic materials for SOFC was investigated. The results of this investigation revealed that the cell ring-on-ring bend test, double torsion test and others were being conducted as tests for SOFC materials and parts as joint research by Rolls Royce, Siemens and others. Tests were conducted in temperatures from room temperature to 900��C an while there was a need for controlling the test atmosphere, it was not implemented. Moreover, it was indicated that the test items that should be conducted will vary according to the shape of the cell, and that the properties of materials for SOFC are not necessarily the same as they were at the time they were measured. On the other hand, users and SOFC ceramic manufacturers in Japan were visited and they were asked what types of property evaluations they actually conducted and whether or not they desired standardization.
(4) Investigation of Patents: An investigation relating to the evaluation of the performance of ceramic laminate structures for SOFC was conducted. Of the patents that were extracted by a patent search, there were patents relating to existing evaluation methods, but the search revealed no patents that were related to future standardization.
