(La0.75Sr0.25)0.95Mn0.5Cr0.5O3 as the cathode of solid oxide electrolysis cells for high temperature hydrogen production from steam
Abstract
Ni/YSZ cathodes are generally utilised for steam electrolysis; however such electrodes can only operate under reducing conditions. In an atmosphere with low content of H2 or without H2, especially under low current conditions, cathodes based on (La0.75Sr0.25)0.95Mn0.5Cr0.5O3 (LSCM) provide a promising alternative. Solid Oxide Electrolysis Cells with LSCM cathodes were tested under external potential load at temperatures between 750 °C and 1000 °C using 3% steam/Ar/4% H2 and 3% steam/Ar, and promising polarisation impedance data were obtained in both atmospheres, especially in the gas without H2. I–V curves from LSCM cells in 3% steam/Ar have sigmoidal shape indicative of chemical changes in the LSCM occurring in addition to electrolysis. Despite these features, considerably improved performance is found compared to Ni-based electrodes in low hydrogen conditions.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
