SOFC (Solid Oxide Fuel Cell)

Product catalog summary

Glass Sealing Tapes

Characteristics: Two types, KeraGlas ST K01 and KeraGlas ST K02, with thermal expansion coefficients (TEC) of 10.6 ± 0.5 ppm/K and 11.0 ± 0.5 ppm/K respectively. Suitable for operating temperatures of 650-780°C and 800-900°C.
Durability: Compatible with various SOFC steels and electrolytes, but not with certain manganese-based compounds.
Key Features: Alkali-free, gastight, long-term stability, and suitable for joining steel/steel or steel/ceramic.

Setter Plates – Keralpor 99 Z

Characteristics: Made from porous alumina coated with zirconia to prevent reactions with nickel oxide. High planarity and porosity allow gas escape.
