Solid Oxide Fuel Cell Interconnects
Fuel Cell Schematic

Interconnects (including current collectors) have a role to connect cells electrically as well as separate air and fuel gas in case of use as separators. The properties required for materials for interconnects are good oxidation resistance, good electrical conductivity, and a coefficient of thermal expansion close to that of electrode materials at operating temperatures (700-1,000°C).

We can provide alloys to meet these requirements developed by our alloy design technologies without peers in the specialty steel market.
