Reversible Solid Oxide Fuel Cells (RSOFCs)

Our technology is based on Reversible Solid Oxide Fuel Cells (RSOFCs) One device that can be operated in 2 modes

  • Solid oxide electrolysis cell (SOEC) mode: SOECs utilize power and heat to convert CO2 and/or water to produce fuels such as carbon monoxide (CO), syngas (H2 + CO), methane (CH4).
  • Solid oxide fuel cell (SOFC) mode: SOFCs can operate with fuels such as hydrogen (H2) carbon monoxide (CO), syngas (H2 + CO), methane (CH4).

In most RSOFC configurations, a different electrocatalyst (electrode) is used at the fuel and oxygen electrodes, which adds manufacturing complexity and cost. Also, most of these catalysts are not very stable in high CO2 and/or water environments.

However, the novel and stable electrocatalyst developed by SeeO2, can be used in both the oxygen-rich environment of the oxygen electrode anode, producing oxygen, and at the CO2/steam environment of the cathode, producing H2 and CO (syngas).

These high-temperature SOECs have clear kinetic and thermodynamic advantages over existing lower-temperature approaches: reactions are faster, the options for alternative catalysts are broader and the catalysts are more stable.
