Activation and failure mechanism of La0.6Sr0.4Co0.2Fe0.8O3-δ air electrode in solid oxide electrolyzer cells under high-current electrolysis

Activation and failure mechanism of La0.6Sr0.4Co0.2Fe0.8O3-δ air electrode in solid oxide electrolyzer cells under high-current electrolysis

This work investigates the activation and delamination of La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF) air electrode of solid oxide electrolyzer cells sintered on yttria-stabilized zirconia (YSZ) electrolyte. After polarization with an electrolysis current of 1 A cm−2 for 24 h at 800 °C, the LSCF electrode delam...
