Low-temperature SOEC stack (700°C operation)

Compact SOEC stacks operating at 700°C with proprietary interconnect coatings for reduced degradation, available in scalable G10/G20/G40 configurations.

Problem solved

High-temperature operation and Cr-poisoning/oxidation degradation in conventional SOEC stacks limit durability and increase system costs for decentralized or modular hydrogen production.

Application contexts

  • modular decentralized hydrogen systems
  • industrial natural-gas replacement pilots
  • maritime e-methane fuel production
  • steel decarbonization support

Technical principle

700°C operation with cobalt-nickel plated interconnects on specialty alloys (e.g., Crofer 22), combined with custom current collectors and seals to maintain performance; stack sizes from 10–40 cells.

Typical use cases

  • small-scale green hydrogen generation for e-methane synthesis
  • evaluation and pilot testing of SOEC modules
