| Research Abstract |
The dielectric properties of inorganic materials in anode gas atmosphere of solid oxide fuel cells (SOFC) at high temperatures (600-850 deg C) were evaluated, and design concepts of primary insulation of SOFC are proposed. The evaluation of DC voltage insulating properties for various inorganic materials shows that magnesia is the best insulation material among them because it has the largest insulation resistance. The effects of anode gas component on dielectric properties were investigated for primary insulation of SOFC composed of magnesia mainly. It is clarified that hydrogen gas itself or heat and flame of hydrogen combustion generated by hydrogen leak degrade primary insulation performance.
