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.
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
