Solid Oxide Electrolysis Cells: Degradation at High Current Densities
Open accessAbstract
The degradation of Ni/yttria-stabilized zirconia ͑YSZ͒-based solid oxide electrolysis cells operated at high current densities was studied.The degradation was examined at 850°C, at current densities of Ϫ1.0, Ϫ1.5, and -2.0 A/cm 2 , with a 50:50 ͑H 2 O:H 2 ͒ gas supplied to the Ni/YSZ hydrogen electrode and oxygen supplied to the lanthanum, strontium manganite ͑LSM͒/YSZ oxygen electrode.Electrode polarization resistance degradation is not directly related to the applied current density but rather a consequence of adsorbed impurities in the Ni/YSZ hydrogen electrode.However, the ohmic resistance degradation increases with applied current density.The ohmic resistance degradation is attributed to oxygen formation in the YSZ electrolyte grain boundaries near the oxygen electrode/electrolyte interface.

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.
