PrototypeCapability Asset

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.

Problem solved

Developers of modular or decentralized e-methane / green hydrogen systems need small-to-medium scale SOEC stacks that operate at lower temperatures with reduced Cr poisoning and custom form factors without relying on major stack suppliers.

Application contexts

  • decentralized hydrogen production
  • e-methane pilot plants
  • industrial natural-gas replacement
  • steel decarbonization support systems

Technical principle

700°C operation using Co-Ni plated stainless interconnects, proprietary current collectors and seals to maintain long-term performance; scalable cell count per customer spec.

Typical use cases

  • prototype SOEC stacks for system integrators
  • performance validation prior to scale-up
