Related capability assets

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.

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.

Custom low-temperature SOEC stack fabrication (700°C class)

Made-to-order SOEC stacks (G10–G40 series) with proprietary interconnect coatings and seals for hydrogen production at 0.4–1.59 Nm³/h scale.

Contract SOEC/SOFC stack performance evaluation (up to 6 kW SOEC)

Independent evaluation service for single cells to 60-cell stacks including co-electrolysis, with visualization and custom gas handling.
