Precision photo-etched SOFC interconnector/separator for fuel cell stacks
Thick-plate photo-chemically etched stainless steel interconnectors and separators for SOFC stacks, with arbitrary flow-channel layout and maintained flatness on sealing surfaces.
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 precision etching of thick (1.0 mm+) stainless steel fuel-cell alloys to form gas distribution channels and flow fields for SOFC/SOEC stacks, maintaining surface flatness critical for stack sealing while allowing custom flow-path geometries.
Application contexts
- SOFC stationary power generator interconnectors
- SOEC electrolysis stack separators
- High-temperature electrochemical stack components
Technical principle
Photo-chemical etching (photolithography + chemical dissolution) of 1.0 mm stainless steel sheets, forming flow channels and gas distribution paths without mechanical stress or burrs. Compatible with specialty fuel-cell ferritic stainless steels (Crofer, ZMG series) for matched CTE.
Typical use cases
- Custom flow-field interconnectors for prototype SOFC stacks
- Precision separators for SOEC stack development
- Thick-plate etched manifolds for stack testing
Partnership route
How global engineering teams typically engage this asset.
Helpful to include: plate dimensions (thickness, width, length) · alloy material required · flow-channel geometry (width, depth, pattern) · flatness tolerance requirement · volume (prototype vs production)
