High Temperature Electrolysis Vessels
Roben, Mfg, Inc. engineers and fabricates high temperature electrolysis vessels for efficient hydrogen production and other electrochemical processes operating at elevated temperatures. Our electrolysis vessels feature materials and designs optimized for solid oxide electrolysis cells (SOEC) and other high-temperature electrochemical systems producing hydrogen from steam.
What Are High Temperature Electrolysis Vessels?
High temperature electrolysis vessels are pressure vessels housing electrochemical cells operating at temperatures from 1200°F to 1800°F where steam is efficiently converted to hydrogen and oxygen. These vessels incorporate cell stack mounting, gas distribution, thermal management, and electrical connections for high-efficiency hydrogen production.

Frequently Asked Questions
Why is high-temperature electrolysis more efficient than conventional electrolysis?
High-temperature electrolysis reduces the electrical energy required for water splitting because more of the energy input can come from heat. At 1500°F, electricity consumption may be 25-30% lower than low-temperature PEM electrolysis, making integration with high-temperature heat sources (nuclear, solar, industrial waste heat) attractive.
What materials are used for high-temperature electrolysis vessels?
Vessel shells use high-temperature alloys compatible with steam and hydrogen at operating temperatures. Internal components including cell stack mounting and manifolds use ceramics and specialty alloys compatible with the electrochemical environment. Sealing systems address high-temperature gas separation requirements.
How is electrical connection made to cells inside high-temperature vessels?
We design high-temperature electrical feedthroughs that maintain gas tightness while enabling power delivery to cell stacks. Ceramic-to-metal seals, appropriate conductor materials, and designs accommodating thermal expansion are critical for reliable high-temperature electrical connections.
