Performance evaluation of a 4-stack solid oxide module in electrolysis mode

To support the current trend of testing bigger reversible Solid Oxide Cell (rSOC) modules, CEA has built 120 kWDC Multistack platform. It was used to test SOLIDpower recently developed-Large Stack Module (LSM) in electrolysis mode. Results show high thermal performance LSM, with homogeneous temperature distribution and losses kilowatt range above 700 °C. A map recorded between 712 744 °C over 22.4-to-29.6 kg h?1 steam flowrates using a fast control strategy avoid endothermic operation. peak power 74 converted into more than 50 day?1 H2 (35.5 kWhDC kgH2?1). In addition, fuel utilization 90% conversion 80% were demonstrated at module level. end, modular design LSM seems well suited for system scale up, paving way mutualization auxiliaries CAPEX reduction.
