DEVELOPMENT OF SOEC STACK FOR HYDROGEN PRODUCTION

抄録

To introduce electricity from renewable energy into the grid a lot, it is required to control the electric power supply. Hydrogen electric power storage is one of the promising candidates for large capacity and long term application. The SOEC method has the highest efficiency of hydrogen production comparing the other conventional technologies. However, the relatively high operating temperature of SOEC causes some difficulties such as degradation of cell and stack materials. In this paper, the SOEC test stack was fabricated with two kinds of seal materials. The gas seal and durability properties of the SOEC test stack were studied.
