Ceramic springs for high-temperature SOFC/SOEC stack compression and sealing
All-ceramic coil springs that maintain constant compressive force at SOFC/SOEC operating temperatures (600–1000°C), enabling reliable gas sealing and electrical contact in cell stacks without creep or permanent deformation.
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
Metal springs relax and creep at SOFC/SOEC operating temperatures above 600°C, causing loss of stack compression, increased contact resistance, and gas leakage. Ceramic springs maintain elastic force at up to 1000°C in both air and hydrogen atmospheres.
Application contexts
- SOFC stationary power generation
- SOEC hydrogen production stacks
- rSOC reversible systems
- High-temperature electrochemical test rigs
Technical principle
High-purity alumina/silica ceramic coil springs with near-zero thermal creep up to 1000°C, electrically insulating, corrosion-resistant in air/hydrogen atmospheres. Available in 9 load ratings (2.0–14.0 kgf / 19.6–137.2 N) and custom sizes.
Typical use cases
- SOFC/SOEC stack compression for gas sealing
- High-temperature electrical insulation in stack assembly
- Laboratory test fixtures for cell evaluation
