Phoenix AM provides glass frit perfect for SOFC sealant.
We have secured the thermal cycling safety, similar coefficient of expansion as port, and calcination density for gas sealing required for SOFC sealant.

Structure of Solid
Oxide Fuel Cell

Evaluation on long-term credibility
of sealing material

  • ※ Requirements of glass frit
    - CTE similar to Port(Sus), Cell
    - Stability on thermal cycling condition
    - Calcination density for gas sealing
