Interconnects, an important component comprising SOFCs, function to electrically connect individual cells.
The company said among the characteristics demanded in materials are oxidation resistance over sustained periods of time at certain operating temperature ranges, electrical conductivity, and a coefficient of thermal expansion close to that of zirconia ceramics electrolytes.
For nickel-based alloys, the coefficient of thermal expansion is large.
Hitachi Metals Specialty Steel Company Akitoshi Hiraki said the company can convert energy with a high degree of efficiency, and continues to contribute to the development of an energy-saving society by providing materials and products that create energy’s future.
