SOFC/SOEC interconnector with Co-Ni anti-oxidation coating for high-temperature durability
Custom SOFC/SOEC interconnectors made from Crofer 22 APU/H, ZMG232L/G10, or other ferritic stainless alloys with proprietary Co-Ni electroplating or MCF thermal-spray coating to suppress oxidation and Cr-poisoning at 600–900°C operating temperatures.
AI-assisted directory summary. Technical specifications, performance metrics, readiness and compliance labels are unverified unless individually supported and reviewed. Proposed partnership routes do not establish supplier consent, export eligibility, or willingness to sign an NDA. Confirm claims and test conditions with the linked sources and supplier before procurement or citation.
Problem solved
Enables long-term (>40,000h) SOFC/SOEC stack operation by preventing Cr-poisoning of cathode and limiting contact resistance increase from oxidation on metal interconnectors at high operating temperature.
Application contexts
- SOFC stationary power generation
- SOEC green hydrogen production
- SOEC e-methane cogeneration
- rSOC reversible systems
Technical principle
Co-Ni electroplating or MCF (Mn,Co,Fe)₃O₄ thermal-spray coating forms a protective conductive barrier on ferritic stainless steel interconnectors, maintaining low contact resistance while suppressing chromium evaporation that degrades cell cathodes. Crofer 22 APU/H and ZMG232L/G10 alloys provide matched coefficient of thermal expansion (CTE) to SOFC ceramic cells.
Typical use cases
- Long-life SOFC stationary generator interconnectors
- High-durability SOEC electrolysis stack plates
- Custom Crofer 22 APU interconnectors for stack developers
