抄録

Currently, development of fuel cells is rapidly carried out after measures of new energy production. Fuel cells are power generation devices that are high in power generation efficiency and friendly to the global environment. In this research, we are developing a separator which is a component of fuel cell. We are developing separators with superior characteristics at lower cost than conventional products by manufacturing separator materials by powder metallurgy method using ultrafine metal powder prepared by water atomization method. In this study, we conduct investigation of 1000 hours of exposure using atmospheric exposure tester, investigate the oxide film formed on the surface layer of the developed material and investigate the heat resistance. It was confirmed that Fe - 35Cr - 0.49Si which was the first developed product was not suitable for separator material because SiO2 which is an insulator was formed on the surface layer. In the second developed product Fe - 35 Cr - 0.2 Si, though the suppression of SiO2 was successful, the problem of oxide film peeling occurred. Therefore, in this report, we report the investigation results of developed materials with Y2O3 added, which has detachment inhibiting effect.
