Crofer 22 APU offers a good balance of the properties required for high temperature electrochemistry. This makes Crofer 22 APU a very popular material for interconnects in solid oxide fuel cell stacks. fuelcellmaterials currently offers this material in sheets that are 0.1 mm thick and either 100 mm x 100 mm or 170 mm x 170 mm dimensions.
Typical Use Guidelines
These Crofer sheets are thin enough to easily cut into your desired interconnect shape, or to create smaller test coupons. Crofer is a high temperature stainless steel with a lower chromium constant than other high temperature stainless steels.
Ensure that there is good compression or electrical connection when using and testing with these Crofer interconnects.
