One cell. Two modes.

Generate clean power in fuel cell mode or produce green hydrogen in electrolysis mode.

SOFC - Fuel cell mode

Elcogen cells used in fuel cell mode have demonstrated excellent resistance to thermal cycling and are highly versatile due to their fuel flexibility.

Solid oxide fuel cells generate electricity and heat as a by-product through an electrochemical process using hydrogen or hydrogen-containing fuels. Electrode-supported solid oxide cells feature an anode made from a ceramic-metal composite. The electrodes are separated by a thin ceramic electrolyte with a protective ceramic layer between the air electrode and the electrolyte. An optional air electrode contact layer improves electrical contact and reduces overall resistance.

Elcogen cells have been tested in-house, in research institutions, and in practical applications. They have shown higher electrochemical performance than other commercially available solid oxide cells, achieving over 75% efficiency at the stack level using natural gas (lower heating value) while operating at wide temperature range, starting from 600°C (compared with the industry average of 750–900°C).

SOEC - Electrolysis mode

Elcogen cells in electrolyser mode have demonstrated excellent resistance to degradation. With the optional air side contact layer and improved electrode contact in reversible operation, the efficiency has been shown to reach 80%.

Elcogen cells represent one of the market’s most efficient solid oxide electrolysis technology (SOEC), achieving specific energy consumption for hydrogen production below 3 kWh/Nm³ while operating efficiently at 600–750°C, compared with the industry average of 750–900°C. The cells are suitable for electrolysis, co-electrolysis (co-SOEC), and reversible operation (rSOC).

The electrolysis function of solid oxide cells is not limited to hydrogen production but is also crucial for Power-to-X applications, syngas production and more. By working closely with our customers, we help them customise and integrate our cells into their stacks to meet their specific requirements.

Empowering the energy ecosystem with technology that delivers

Improved system economics: The comparatively low operating temperature supports longer service life while enabling the use of lower-cost materials at stack and system level. The result is improved overall system economics.
With you all the way: We offer integration support covering consultancy on process and system design, advice on balance-of-plant component and material selection, simulations and process calculations with consultation on testing and operation procedures.
Designed to meet your needs: We offer two standard product families (300-C and 400-B). Custom sizes and geometries can also be developed to meet specific customer requirements.
Mass-manufacturing capabilities: Our brand new state-of-the-art 14,000 m² production facility has increased production capacity to 360 MW, positioning the company as one of Europe’s largest manufacturers of high-efficiency SOFC and SOEC technology.

rSOC - Reversible SOC

Our reversible SOC technology allows for the same system to run in both fuel cell and electrolysis mode. 

This reversibility is seen as a strong disruptive innovation, that can enable a dramatic CAPEX reduction in a power-to-power chain, as only one asset is needed, instead of the two required in a standard power-to-X-to-power chain.
