Cr-poisoning prevention coating for SOFC/SOEC interconnects and current collectors
Co-Ni plating and MCF thermal-spray coating services for ferritic stainless steel interconnects, suppressing Cr evaporation and contact-resistance rise in SOFC/SOEC stacks.
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
Prevents cathode performance degradation caused by Cr evaporation from ferritic stainless steel interconnects at 700-800°C, maintaining low ASR and long stack life.
Application contexts
- hydrogen
- energy-conversion
- industrial-equipment
Technical principle
Co-Ni alloy electroplating or MCF (MnCoFe-oxide) thermal spray coats the interconnect surface, forming a barrier that reduces Cr vapor pressure and stabilizes contact resistance over thousands of hours.
Typical use cases
- Co-Ni coating of Crofer 22 APU/H interconnects for SOFC stacks
- MCF thermal-spray coating for large-area interconnect plates
- Custom coating of current collector meshes and porous metals
